Mexican Pizza

This recipe I took from allrecipes.com. It's super easy and fast. Everyone loved it and the presentation is great too!

1/2 lb ground beef
1 medium onion, diced
1 clove garlic, minced
2 tsp chili powder
1 tsp ground cumin
1/2 tsp paprika
1/2 tsp black pepper
1/2 tsp salt
1 (16 oz) can refried beans
4 flour tortillas
1/2 cup salsa
1 cup shredded Monterey Jack cheese
2 green onions, chopped
2 tomatoes, diced
sliced olives

Preheat oven to 350 degrees. Coat 2 pie plates with non-stick cooking spray.
Place beef, onion and garlic in a skillet over medium heat. Cook until beef is evenly browned. Drain off grease. Season the meat with chili powder, cumin, paprika, salt and pepper.
Lay one tortilla in each pie plate, and cover with a layer of refried beans. Spread half of the seasoned ground beef over each one, and then cover with a second tortilla. Bake for 10 minutes.
Remove the plates from the oven, and let cool slightly. Spread half of the salsa over each top tortilla. Cover each pizza with half of the cheese. Place half of the tomatoes, half of the green onions, and half of the olives on each one.
Return the pizzas to the oven, and bake for five to 10 more minutes, until the cheese is melted and edges brown slightly. Remove from the oven, and let cool slightly before slicing.
