Taco Ring from Pampered Chef

This is one of Dave's favorite dinners!

3/4 pound ground beef
1 package taco seasoning (1.25 oz)
1 cup shredded cheddar cheese (4 oz)
2 tablespoons water
2 packages refrigerated crescent rolls (8 oz each)
1 medium green bell pepper
1 cup salsa
3 cups shredded lettuce
1 medium tomato, seeded and chopped
1/4 cup chopped onion
1/2 cup sliced pitted rip olives
Sour cream for garnish

Preheat oven to 375 degrees. Brown beef and pour in seasoning mix, cheese and water. Set aside. Unroll crescent dough; separate into triangles. Arrange triangles in circle on greased 14-inch pizza pan with wide ends overlapping in center and points toward outside. (There should be 5-inch diameter opening in center.) Scoop meat mixture evenly onto widest end of each triangle. Bring outside points of triangles down over filling and tuck under wide ends of dough at center. (Filling will not be completely covered.) Bake 20-25 minutes or until golden brown. Cut top off bell pepper using a V-shaped zigzag pattern. Place pepper in center of ring; fill with salsa. Mound lettuce, tomato, onion and olives on top of ring surrounding bell pepper. Cut ring; serve garnished with sour cream.
