Preheat oven to 450. Prepare your tortillas by drizzling olive oil on them, coating both sides. Place in oven to toast for 5-10 minutes, checking frequently. They will go from perfectly done to burned rapidly.
While your tortillas toast, dice the steak into 3/4 cubes and season with the spice blend, reserving a pinch to season the vegetables.
Then prep your pepper, onion, and garlic.
In a large skillet heat 2 tablespoons of olive oil and sear the sirloin on medium-high, for 5-6 minutes until golden brown. Remove the steak and leave the brown bits in the pan.
Add the diced pepper, onion and garlic with the remaining spice blend. Cook on medium-high, string occasionally, 2-3 minutes, or until slightly softened.
Add 1/2 cup of water and cook stirring occasionally, 2 to 3 minutes or until thick and saucy. Once you have a thick sauce and soften veggies, add your steak back into your skillet and a squeeze of one lime wedge.
Use the rest of the lime in your Mexican Beer!While the sauce cooks, top your toasted tortillas with the Monterey Jack cheese and pop them back in the oven for 2 to 3 minutes to melt the cheese
Assemble the tostada by adding the finished steak and veggies to the tortilla top with the Cotija cheese and sour cream. Garnish with a lime wedge and enjoy!
Notes
Sometimes we can’t find Cotija cheese so we substitute it for Queso Fresco.
