First, the recipe from the cookbook.
I mixed all three cans of tomato product first (can someone help me understand the benefits of the three types? The tomato paste just seems so small in comparison to the rest, but I'm sure there is some benefit to this.) Then I added all the seasonings and mixed those in. Next came the onions and bellpeppers - mostly because I wanted to cut those up before messing everything up with the raw chicken. I have a thing about raw chicken - I use 409 extensively after cutting it up no matter how careful I am.
Anyway, the chicken went in last, and definitely filled the 4qt bowl. (The recipe recommends 3 qt, but I seriously doubt all of this would have fit in a 3qt bowl. My 4qt bowl was filled pretty near the top.)
