I spend a fair amount on groceries, but not as much as some of ya'll.
I try to buy in bulk for most of my meat/protein items, and use garden-fresh veggies and fruit when I can. We don't eat steak and lobster, but I am not going to punish my family by feeding them hot dogs and ramen noodles all of the time.
Tonight, for instance: baked bar-b-que chicken, fresh green beans, and rice pilaf. Nothing fancy, but homemade, nutrituous, and tasty.
Tomorrow, I'll use the rest of the green beans for a pot of green beans with ham and potatoes. Again, nothing fancy, but tasty, easy and economical.
Wednesday, I'll probably cook up a roasted chicken with some new potatoes. Cheap and easy. Just like me.
Now, I will splurge and cook a really nice meal periodically, but that is a somewhat rare occurrence these days.
You can take an inexpensive piece of meat and season it up nicely, and elevate it in to something positively delicious....without it costing a fortune. Remember, you best friend when cooking economically is utilizing wonderful, tasty spices/rubs/sauces.
