Dice carrots and potatoes and cook until just tender in the stock.
Chop onions.
Cut brocolli and cauliflower in bite-size pieces.
Add Cheese Whiz to stock.
Prepare roux with butter and flour. You need generous amounts. Use at least one stick of butter, even two. Stir into stock.
Season to taste with salt, pepper, and paprika (A spicey and/or smokey paprika is nice.)
Add brocolli, cauliflower, onion, and cooked meat and simmer until onion is transparent.
Serve with a really good bread.
