Beef Tostadas Supremas

Adjust rack to top position (top and middle positions for 4 servings) and preheat oven to 450 degrees. Wash and dry produce. Halve, core, and thinly slice green pepper crosswise into strips. Halve and peel onion; thinly slice one half. Finely chop remaining half until you have 2 TBSP. (For 4 servings, thinly slice both onion halves; finely chop a few slices until you have 3 TBSP.) Dice tomato. Zest and quarter lime.

Heat a drizzle of olive oil in a large pan over medium-high heat. Add pork* and Southwest Spice Blend; cook, breaking up meat into pieces, until browned, 3-4 minutes (it’ll finish cooking in the next step). TIP: If there’s excess grease in your pan, carefully pour it out. Swap in beef* for pork.

Add green pepper and sliced onion to pan with pork. Cook, stirring occasionally, until veggies are tender and pork is cooked through, 5-7 minutes.Add Tex-Mex paste and ¼ cup water (⅓ cup for 4 servings). Bring to a simmer and cook until thickened, 1-2 minutes. Season with pepper. Cover to keep warm.

While pork mixture cooks, drizzle tortillas with 1 TBSP olive oil (2 TBSP for 4 servings); brush or rub to coat both sides. Arrange on a baking sheet in a single layer. Gently prick each tortilla in a few places with a fork. (For 4, divide tortillas between two sheets; toast on top and middle racks, flipping tortillas and swapping rack positions halfway through toasting.) Toast on top rack, flipping halfway through, until lightly golden, 4-5 minutes per side. TIP: Tortillas brown quickly—keep a close eye on them.

Meanwhile, in a small bowl, combine tomato, chopped onion, juice from half the lime, and a pinch of salt and pepper.In a separate small bowl, combine sour cream, a squeeze of lime juice, and a pinch of lime zest to taste. Stir in water 1 tsp at a time until mixture reaches a drizzling consistency. Season with salt.

Remove baking sheet with toasted tortillas from oven; carefully sprinkle with Mexican cheese blend and Monterey Jack. Return to oven and bake until cheese melts, 1-2 minutes.Divide cheesy tortillas between plates and top with pork mixture and pico de gallo. Drizzle with crema. Serve tostadas with any remaining lime wedges on the side.
