Here are a few inexpensive cook-in-bulk things I've done recently. I'm mostly cooking for one, so anything I make in bulk has to be something I
really like.
Red beans & rice. Smoked hocks were on sale over the holidays. I have two more! One of those will go into a batch of collards. Not sure what the other one is going to.
Chicken & red lentil soup. I threw in some lacinato kale. For some reason there was a shortage of chicken thighs in my store---none
at all. I used bone-in/skin-on turkey thighs instead.
My grocery had boneless top round on sale for $6/lb. I've got a 2.5 lb roast sitting in the fridge now with a salt, pepper, garlic, and rosemary rub. That's going in the oven later today to set me up with roast beef sandwiches.
