In a large skillet heat olive oil.
Add ground beef and taco seasoning and cook until meat has browned. Remove from heat and set aside.
Preheat oven to 375 degrees.
On ungreased large cookie sheet, arrange crescent dough triangles in ring so short sides of triangles form a 6-inch circle in center. Dough will overlap.
Spoon ground beef over wide section close to center. Sprinkle cheese on top.
Bring each triangle tip up over filling, tucking it under bottom layer of dough to secure it.
Bake for 20-25 minutes or until ring turns a golden brown.
Allow to cool for 5 minutes before slicing.
Place a bowl of guacamole and salsa in the center of the ring for dipping.
Garnish with shredded lettuce, if desired.
