One of my favorite things to make is a vegetable soup. It's filling and it's cheap (and that is the best part) I make it little thicker than a soup although you can tweak it easily to make it more of a soupier consistency.
- A bag of frozen mixed vegetables $1
- A jar of spaghetti sauce $1
- A box of noodles (usually I use radiatore, but I used cavatappi this time) $1
- Can of diced tomatoes $. 75
And that's it.
I cook the noodles until they are done, then mix everything into a crockpot and let it cook on high for a few hours.
I use spaghetti sauce since it's the same thing as tomato soup (although I do occasionally add a can of that as well), and I only use half of the box of noodles.
I also will add other veggies if I have them on hand (such as onion or pepper). Basically you can use up what you have in the house.
I make this meal every few weeks, and if there are leftovers freeze them in individual portions for me to have for lunch.
