1 lb Lean ground beef 
1/2 c Chopped onion 
1 Clove garlic, minced or pressed, optional 
1 ts Salt 
1/2 ts Chili powder 
2 c Diced tomatoes 
4 lg Wheat flour tortillas 

Direction:
Oil for trying tortilla. Brown together ground beef, onion and garlic in a heavy frying pan over medium heat, stirring until meat loses its pinkness. 
Add salt and chili powder, blending well. Place 1/2 cup of the ground beef filling. 1/2 cup shredded chasse and 1/4 cup diced tomatoes onto one-half of each tortilla. Fold other half  filling, pressing it down to remove any air pockets. Pour oil into large skillet to 1/4 inch depth. When oil is hot, place filled tortillas into pan a few at a time. Sauté over medium to high heat until golden on each side, about 45 seconds per side. 6. Remove from pan onto paper toweling. Cut into wedges to serve.
