How about --
Low fat black refried beans and a little shredded cheese melted into yummy goodness.
Cream of Wheat made with 1% or skim milk (that's where the protein is).
Sugar free, fat free pudding (lemon is my favorite, but there's no protien in that).
If you have a Ralph's or Kroger grocery store - the CarbSmart Yogurt is really good and protien powder mixes in really well with that.
I'm sure there is a list of food somewhere else on the forum. Do a little searchng and see what comes up - or look in the recipe section?!

Goodluck!
