Preheat oven to 400 degrees F.
Roll out the 3 tubes crescent rolls onto a greased cookie sheet (I used a 17×11 cookie sheet). Bake at 400 for 10 minutes or until crust is a light golden brown.
While the crust is baking, mix together the softened cream cheese, mayo and ranch seasoning packet.
Chop up the veggies. (you will probably end up with some extra veggies so you might want to buy a head of lettuce and toss the left over chopped veggies with the lettuce to make a quick salad)
When the crust has completely cooled, spread the dressing on dough and then cover dough with veggies (in my opinion the more veggies the better).
Before serving, sprinkle on the shredded cheddar cheese, then cut into squares.
