Chickpeas, also known as garbanzo beans, are an excellent source of cheap protein. Pair them with basil from your garden and sweet grape tomatoes when in-season, and you’ve got a frugal salad that’s also really healthy. I found these tomatoes at my ALDI store for just $.79 this week (view more recently posted Grocery Bargains). You could also easily add rotini to this to make it a pasta salad. Frugal Tips: To save money, buy dried chickpeas and soak overnight.
