This is from one of my aunts (actually a second cousin I believe, but who cares) and it is delicious!
Refrigerated crescent roll
8 ounces cream cheese
1/2 cup mayonnaise
3/4 teaspoon dry onion
1 teaspoon dill weed
Veggies of your choice on top (celery, broccoli, carrot, cucumber, cauliflower, etc)
Heat oven to 400 degrees. Open and unroll the crescent roll, but don't split into pieces! Place on cookie sheet and bake for 10 minutes and let cool. Mix the cream cheese, mayonnaise, dry onion, and dill weed; spread on top of cool crust. Top with vegetables of your choice. Place desired amount of mozzarella cheese over veggies!
