1 c. water
1/4 c. plus 2 tbsp. picante sauce, divided
12 corn tortillas
2 lbs. ground beef
1 onion, chopped
1 to 1 1/2 tsp. salt
1/8 tsp. pepper
2 tsp. ground cumin
1 tbsp. chili powder
1 tsp. garlic powder

Combine water and 2 tablespoons picante sauce in a large shallow dish. Place tortillas in picante sauce mixture; let stand 5 minutes. Drain.

Cook ground beef and onion in a heavy skillet until brown; drain off drippings. Stir in salt, pepper, cumin, chili powder, garlic powder, olives, and 1/4 cup picante sauce; simmer meat mixture 5 minutes.

Melt butter in a heavy saucepan over low heat; add flour, stirring until smooth. Cook 1 minute, stirring constantly. Gradually stir in milk; cook over medium heat, stirring constantly, until thickened and bubbly. Remove from heat, and add sour cream; stir until well blended.

Place half of tortillas in a 9x13x2 inch baking dish. Pour half of sour cream sauce over tortillas; spoon half of meat mixture evenly over sauce. Sprinkle half of cheese over meat mixture. Repeat layers with remaining ingredients. Bake at 375 degrees for 25 minutes. Serves 8.
