Moroccan Harira (Bean Soup)
A (mostly) vegetarian, shoestring-budget meal that will leave you feeling both very satisfied and with tons of leftovers. Bonus: it's super-healthy and easy to prepare.
To make the soup wholly vegetarian, trade out the beef stock for vegetable stock.
If you do use quinoa, be sure to prepare it separately from the soup (1/2 cup unprepared = 1 cup prepared). Throwing it into the soup unprepared will cause it to absorb all the liquid and you will be left with a very, very thick stew.
