The two things I remember my mom cooking most was tuna and rice (Simple, cheap & quick) and salmon patties fried up in that old cast iron skillet. Those things would stink up the house for 2 nights.
Dinner menu in my house was pretty much the same week to week.
Sunday - Pot roast, mashed potatoes and carrots. (Could also be pork roast, roast chicken)
Monday - Hash from the leftover sunday meal
Tuesday - Meat sandwiches (or baloney or PBJ if the Sunday leftovers ran short)
Wednesday - Tuna casserole - tuna, some kind of cream sauce, maybe peas, buttered toast on the top
Thursday - Hamburger and beans or hotdogs and beans - I made this for my kids a few weeks ago and they turned their nose up at it.
Friday - Kentucky Fried Chicken sometimes. The rest of the time veal cutlets and mashed potatoes or salmon croquettes. I wish I had a veal cutlet right now.
Saturday - Whatever grandaddy grilled - usually burgers but sometimes steaks.
That's about it. Sometimes we'd have a lemon meringue pie or a pound cake. I don't remember candy, pies, cakes or dessert ever being much of a thing. We never even had cookies laying around unless they were homemade oatmeal.
Breakfast was always oatmeal or cereal (Quisp, Capn' Crunch, Rice Krispies, Froot Loops, Apple Jacks, Corn Pops, Raisin Bran or Sugar Smacks - and there was only one box in the house until it was gone so when the box was Raisin Bran, I sulked like a bitch because I hated the FUCK out of raisin bran) and with toast or on special occasions a pop tart.
