Spray Pam in 9x13-inch pyrex pan or baking dish. Separate crescent rolls into two parts and lay in bottom of baking dish pushing together and stretching to make one solid sheet. Bake according to temperature on package but watch time.
When cool, spread with sour cream mixed with party dip. Add meat and layer lightly whatever else you choose to use. Cheese on top. Refrigerate over night. Keeps well.
Notes
Be sure everything is dry as you use it. use a lot of paper towels to drain everything so it doesn't get soggy.
