Step 1

Preheat the oven to 350°. Line a rimmed baking sheet with parchment, Silpat, or foil and spray with non-stick cooking spray.

Step 2

In a large skillet, cook beef, onion and garlic over medium-high heat until beef is browned and onion is tender. Drain grease. Stir in chili powder, cumin, salt, pepper, and cayenne.

Step 3

Place two tortillas side by side on baking sheet, and cover with a layer of refried beans. Scatter half of the seasoned ground beef over each tortilla, and then cover with a second tortilla.

Step 4

Bake 10 minutes. Remove the baking sheet from the oven.

Step 5

Spread salsa on top of each top tortilla stack. Top with cheeses, tomatoes, green onions, and jalapenos.

Step 6

Return the pizzas to the oven, and bake for 5 to 10 more minutes, until the cheese is melted. Remove from the oven, and let cool slightly before slicing each one into 4 pieces.
