Garbanzo Bean salad.
-Garbanzo Beans (chick peas)
This is a very healthy salad that you can eat as a meal or snack. It's cheap too if you can get your produce for a good deal. You can get the beans canned. If they're canned, rinse them before hand. Bagged beans are cheaper, but you need to boil them for a couple of hours before hand.
For me this meal would cost about 4 dollars assuming you own seasonings, lemon juice, and olive oil. And you can eat it 2-3 times a can. So that's a bit over a buck a meal.
Basically, you throw everything in to a bowl. Mix it up and adjust the taste to your preferences. It stays cold in the fridge. You can also use italian dressing if lemon and olive oil is too boring for you
Hope you like!
