The main reason that tacos are so cheap for us is that we deer hunt and grind most of the meat ourselves. So instead of ground beef we use ground venison for tacos. I also can my own salsa in the summer from home grown tomatoes or tomatoes from the farmers market. So all I have to by are the taco shells, cheese, lettuce, sour cream and any other fixings that we want. I buy taco shells at Aldi for $1.00 a box ( we use two), sour cream from Aldi for $1.19, cheese from Sams Club for $12.00 for five pounds (so we spent about $2.00 for the tacos), and we buy lettuce from Sams for three dollars for six heads of romaine (so about .50 for the lettuce). The seasoning we buy in bulk, but it can't be more than .50. So I calculate that for less than $7.00 our whole family can eat tacos.
In this picture are some grapes that were going to go bad, so we put them out. We will sometimes buy a $2.00 bag of chips and eat them with the salsa or buy some avocados if they are on sale and make some guacamole. Yummy!
This meal will feed us and a few extras if needed. We usually have some flour tortillas around that I can get out if need be. So you see, you can feed a big family for cheap and they will eat it. I will try to include some other money saving meals throughout the summer.
