Just checkout the Walmart website; a bag of onions is $2, carrots is $.80, and celery is $1.30. one pound of minced beef is $3.70 tinned tomatoes for $.50 and spaghetti is $0.80. that's a meal for 4 for $9 and takes ~30 minutes to prepare and clean up.

Cooked well, that will lead you to a bland meal. Cooked badly it will be pretty awful. If you're used to high in salt/sugar it will taste awful regardless.

Craft Mac and cheese is $1/portion and ready in less than 10 minutes with one dish.
