What I used:
I ended up doubling the recipe. It only calls for half that box of macaroni, and half that bottle of tomato juice. I also added salt & pepper.
There was more cheese to add to individual bowls. My normal goulash does not use vegetables, chili powder, or cheese, and I usually use canned whole tomatoes and a little spaghetti sauce instead of the juice and tomato sauce. I like the addition of vegetables and will probably do that in the future - although I'll use frozen instead of canned, it is cheaper. We loved the addition of cheese, and the chili powder is a nice touch.
The Recipe Drawer
When we bought the farm from my mother in law, it came with a recipe drawer. Her recipes, recipes from aunts, friends, sister in laws, mostly in family members handwriting. My daughter & I have been working through the drawer, trying as many of the recipes as we can.
