Beef Tostadas w/ Fresh Salsa

I've been craving mexican food lately so that was my inspiration for this quick and easy dish.

Serves 2-4

2-4 flour tortillas
1 pound ground beef (don't exceed 15% fat)
1 teaspoon olive oil
1/4 cup white onion, finely chopped
1 clove garlic, minced
1/2 teaspoon salt
1/8 teaspoon ground black pepper
1/2 teaspoon ground cumin
1 tablespoons chili powder
1/4 teaspoon oregano
2 tablespoons jalapeño peppers, chopped
1 can Rotel (diced tomatoes w/ green chilis)
2 tablespoons tomato paste
1/3 cup water
Mexican Four Cheese, shredded
Lettuce, shredded (I used romaine hearts)
Sour cream
Salsa (see recipe below)

1. In a large skillet over medium heat, brown the meat in the olive oil.
Pour off any excess oil. (If you're using ground round, there shouldn't be any excess, but drain whatever is there.)
2. Add the onion, garlic, salt, pepper, spices, jalapeños, Rotel, tomato paste, water, and stir well. Lower heat, cover and simmer for 10 minutes. While filling is simmering, in a separate skillet, add some canola oil and heat on high until hot. 
3. Add the flour tortilla and cook on both sides until crisp.
4. Top the crispy tortilla with meat mixture, then top with cheese, shredded lettuce, salsa and sour cream.

Salsa:
Grape tomatoes, chopped
Onion, chopped
Jalapeno, chopped
Cilantro, chopped
juice of 1/2 lime
salt

1. Mix all ingredients in bowl.
