Bake 400 degrees 25 min use wire rack on baking sheet to bake up crisp. 1# gr beef, sm onion, taco seasoning--let meat cool. Add 2 c cheese, 1 c sour cream, 1/2 c salsa. pread across shell and roll up tightly and secure with toothpick before putting on wire rack over cookie sheet.
Highly Recommend: Chipotle Beef Taquitos. You make the beef by doing a french dip meat in the crockpot. Then use the leftover meat the next day. They're so much better than store bought. I've done it with queso fresco and blanco.
