Preheat oven to 375°F (190°C).

Roll out crescent rolls on a cookie sheet.

Bake for 7-8 minutes, or until golden brown.

Let the baked crust cool completely.

In a bowl, mix cream cheese, Miracle Whip, and Hidden Valley Ranch mix until smooth.

Spread the cream cheese mixture evenly over the cooled crust.

Finely chop broccoli, onion, cauliflower, and tomatoes.

Sprinkle the chopped vegetables over the cream cheese layer.

Gently press the vegetables into the cream cheese mixture to secure them.

Cut into squares and serve.
