Grocery shopping got a lot faster since I stopped looking at Everything and just buy the stuff on my grocery list. I do like to look in the deli, but usually for ideas on what to make at home.
Injected or brined meats including most grocery stores rotisserie chicken. I once bought some spare ribs that were pre treated, and didn't realize it. Learn to read the meat labels now too. And No, I do not buy pre-sauced heat and serve foods. I make better sauces (and so do you).
I have an aversion to ground chicken, but buy ground turkey.
Those box things Steve pictures are wa-ay too salty. A relative uses them when we come to dinner. I take the Polite size portion.
Pre package mixes - I do buy Lipton's french onion soup mix. I know, it's just as salty, and those boxes of Knorr vegetable soup mix? for spinach dip. I pretty much quit buying canned soups, like chix noodle, veg beef etc. I think they taste too salty and tomato soup is too sweet. I also Can't find a decent ketchup and now think Heinz is too sweet too. I think my flavor tastes have altered.
I Run the other way when I see Cool Whip. Not sure which of the 4 food groups it goes in. It's not beer, bacon, ice cream or chocolate.
