Unroll crescent roll dough into a greased 15x10x1-in. baking pan. Seal seams and perforations; press dough up sides of pan. Prick with a fork. Bake at 375° for 11-13 minutes or until golden brown; cool on a wire rack. In a bowl, beat cream cheese, mayonnaise and seasonings until smooth. Stir in cheddar cheese, green pepper, mushrooms, onion and olives. Spread over crust. Sprinkle broccoli over "field" to within 2 in. of each short side. Sprinkle end zones with chopped tomatoes and mushrooms. Set aside 2 tablespoons cream cheese. Place remaining cream cheese in a small heavy-duty resealable plastic bag; cut a 1/4-in. hole in one corner. Pipe yard lines every 2 in. over broccoli. (A small amount will remain in bag; set aside.) For helmets, cut an opening in mushroom caps; carefully clean out. Cut opening in cherry tomatoes on paper towels. With a 3/4-in. circle cutter, cut seven circles from each slice of cheese. Insert American cheese circles into mushrooms and Swiss circles into tomatoes. Cut a very small hole in a different corner of reserved bag. Pipe cream cheese lines onto tomato helmets and laces onto olive. In another small plastic bag, combine food coloring and reserved cream cheese. Cut a small hole in one corner; pipe lines on mushroom helmets. Place all helmets on field with olive football in middle.
