Begin by preparing the steak marinade. Combine all ingredients into a medium sized bowl and stir until completely mixed. Next, cut the steak into 1/2″ cubes and place them into the marinade, cover the bowl and refrigerate for 1-2 hours.
Remove the steak from the refrigerator and allow it to just reach room temperature before moving on to the next steps.
While the steak is marinating prepare the other ingredients.
Shred the red cabbage. Be sure not to shred the cabbage to finely. A medium shred should do just fine and create an additional wonderful layer of texture for this dish.
Dice the tomato and the jalapeño, and cut up the scallions, separating the white part from the green.
Cut the lime in half and then take one of the halves and cut it into quarters. Do worry about cutting the other half up, we are going to be using that half for juice only.
Chop up the garlic and cilantro, and then slice the avocado in half and remove the skin and seed. If you have some you can put a little lemon juice on the avocado to prevent it from browning before we assemble the dish.
For this dish you can roast or grill the corn before removing the kernels from the cob, for a nice smoky accent. I have chosen to prepare mine a bit differently this time. Remove the corn kernels from the cob and set them aside. Heat a medium size pan over medium heat, place 1 tbsp of olive oil and add the garlic, cook for 1 minute and then add the green portion of the scallions and cook for 1 more minute. Add the corn kernels to the pan with salt and pepper and cook until he kernels are tender. Remove the pan from the heat and set it aside once corn is done.
Alright, let’s prepare the yummy slaw for this dish
Combine shredded lettuce, the reserved green scallions, the reserved cilantro, jalapeños and ranch dressing in a bowl.
Squeeze the juice from the 1/2 of lime into the bowl and the vinegar, and add a 1/4 tsp or salt and 1/4 tsp pepper to bowl. Mix all ingredients until well combined. Set slaw aside.
Now it’s time to get the beans ready
Pour the beans from the can into a colander and rinse thoroughly.
Place the beans into small pot and fill with enough water to cover an inch above the beans, add a dash of salt and warm beans over medium heat for 5 – 7 minutes. We want the beans to be very tender so that they can be easily mashed.
Once the beans are very tender, but not falling apart, strain off the water in the pot and return the beans to the pot. Add the chicken broth to the pot and mash beans with a potato masher until they are the consistency of refried beans.
If you purchased blocks of cheese, now is the time to shred the cheeses and set the shredded cheese aside for later. While I prefer to purchase block cheese, pre-shredded in the bag works just as good.
We are rounding third now on the preparation process and we need to get that meat cooking so we can get eating these delicious tostadas
Heat a large pan on the stove over medium high heat. If you prefer and you have the time, grilling the steak is a great option. Either way will taste delightful.
Add 1 tbsp of olive oil to the heated pan, and carefully place the steak into the hot pan. Be careful, when adding the meat.
Sear meat 3 – 5 minutes, turning occasionally until all sides of meat are browned and steak is cooked to medium well on the inside.
Once cooked, remove the steak from the pan, place on a dish and set it aside.
Using the same pan, wipe the pan out and then add the remaining oil to the pan. Reduce the heat to medium and one by one add the tortilla’s to the oil until all are cooked to a crisp texture, but not browned.
Drain the tortilla’s on paper towel.
Plate the elements: Equally divide the prepared elements of the dish between two plates and serve. Allowing each person to assemble their own tostada’s is a creative fun way to serve this delicious dish.
Time to Assemble: complete the following steps for each tostada
Smear some of the black beans onto the tostada, almost to the edge. The beans will act as a binder to help keep the other ingredients from falling off the shell.
Sprinkle on some of the white cheddar and yellow cheddar cheeses onto the tostada
Sprinkle on some of the corn and add several cubes of the cooked steak.
Top the tostada with the red cabbage slaw, tomatoes, and salsa
Garnish with avocado slices and sliced lime wedges
