I cobbled together this recipe today. It's so yum!

Ingredients:
24 ounces of Broccoli/Cauliflower mix (I used a 12oz bag of each)
4 celery sticks, chopped
Water
6-8 oz heavy cream
8-10 oz cheddar cheese (I used shredded)

Add veggies to a pan and cover with water.
Bring to a boil and cook 15 mins.
Turn to medium heat.
Pour out half the water.
OPTIONAL: Take a stick blender or hand masher and mash 2/3 of the veggies into a thick pulp. This will help your soup stay thick.
Add cream, cheddar cheese and salt/pepper to taste.
Cook just until cheese is melted and serve! I add either a small amount of cheese or sour cream on top.
(If its too thick, just add a bit of water.)

Makes 8 servings.
