We didn't have any taco shells, so I decided to breakout the old pizza starter instead, so I guess that you can call this being pseudo-frugal, As you can see from the shape, I've given up, for now, on the round pizza variety and decided to play it safe and just form the dough into the shape of the baking tray. Hey, on the highway of life, if it's easy, I'll take that off-ramp.
I pre-bake the crust (you can use the pizza dough recipe from My Pizza Dough Recipe and after it cools, I slather on the sour cream and then sprinkle the cheese over the top. I cook the meat and once it cools, I spread that over the top and then cover with the remaining cheese and bake.
Anyway, here's the cost breakdown of this meal:
Spices...I have no idea, but it's under $1.00 (I make my own taco seasoning)
Total...$10.48 (I just added the $1.00 for the seasoning)
Okay, I can see that you might be saying, "what's so frugal about that???" That's kind of pricey for a meal. Well, I would have to agree, but this wonderful pizza provided three meals for my family. The per-meal cost for each person was: $1.16.
($10.48 / 3 people= $3.49 / 3 nights = $1.16)...not too bad, actually.
