2 pounds ground beef
2 (8 ounce) packages cream cheese, room temperature
2 (8 ounce) packages shredded Cheddar cheese
2 cups mayonnaise
1 (8 ounce) package frozen chopped spinach
1 head lettuce, broken into thirds
Preheat oven broiler.
In a large bowl, mix together graham cracker crumbs, cream cheese and Cheddar which will thicken. Spread 1/2 of the mixture into each tortilla.
Mix 1/2 of the cream cheese mixture with 4 ounces of unseasoned mayonnaise. Spread 1/2 of the mixture on each tortilla, then layer the remaining cream cheese mixture over them. Press flat all other ingredients together and press any dough down to blend.
Bake in preheated oven 20 minutes, or until golden and crusty.
