Crock Pot Incredibly Easy Recipes. This was definitely one of those recipes where my roommate and I questioned why one might want to make this in the crock pot in the first place because it doesn't cook all day (only takes about 2-3 hours) and it might just be faster if you made it on the stove.
Here is the crock pot once I stirred it the first time.
And here is the mac and cheese once it was done cooking.
However, it definitely fits into the "cheap food" category. The pasta was on sale when I got it--10 for $10 of Barilla pasta--so it comes out to be less than $0.95 per serving (assuming one already has skim milk). Even when I added the canned tomatoes ($0.73 for store brand), the final four servings were still less than $1.15 per serving.
