1/4 teaspoon oregano
1/4 teaspoon cumin
1/4 teaspoon chili powder
1/4 teaspoon garlic powder

Brown beef, drain. Combine with remaining ingredients, except tortillas and Jack cheese. Layer in greased 9x13-inch baking dish with 6 tortillas, meat mixture, 6 tortillas and meat mixture. Top with Jack cheese. Bake uncovered at 325 for 30 minutes.
