To make salsa, to 1 cup water, add 1 beef bouillon cube, 2 or 3 tablespoons chili powder and 2 tablespoons lard or bacon grease. Heat mixture until it boils. Reduce heat and gently boil 5 minutes. To make the Cheese and Onion Mixture: grate 1 pound cheddar cheese. Add 1 medium chopped onion. Dip each tortilla in salsa, coating each side. Immediately spoon cheese and onion mixture onto tortilla and roll up. Place filled tortillas in greased baking dish. Pour remaining salsa over tortillas. Bake at 300° for 10 minutes, until cheese melts.
