I adjusted a recipe from Parents magazine and made this last night. I gotta say, I'm pretty impressed ...
3 potatoes, diced into 1/2 inch pieces
3 cups frozen broccoli
2 cans vegetable broth (or about 3 cups)
dash of onion salt
3 cups monterey jack cheese, shredded
In medium saucepan, bring potatoes, broccoli, vegetable broth and onion salt to a boil. Drop heat to medium and simmer about 10 minutes or until potatoes are soft. Left cool about 5-10 minutes.
Blend soup with the cheese. I put about 1/3 of the mix in blender with 1/3 of the cheese and then kept layering until my blender was about 2/3 full, then I pureed. Add a little more mixture little by little until all is blended. (I mixed the last portion in unblended because I like some chunks.)
I didn't think my family would eat it because it looked like green glump, but my 2-year-old downed three bowls. We'll be making it again.
