YES MAJORLY! Before my divorce, so two adults, one small kid... We were spending upwards of $150-200 each trip. Don't judge haha. I brought that down to $75-125 by meal planning.

You don't have to eat the same thing every day. My son and I eat a different dinner every day. Sometimes the same ingredients, but you can really change it up. I don't follow any of those meal prep groups but that would probably really help, or if I had freezer space, I'd do those crock pot freezer meals. I try to do for dinners in a week: 2 chicken, 2 beef, 1 fish, 1 or 2 vegetarian, 1 pork or 1 more chicken or 1 egg based. Something like that (my son needs the protein and iron and can't send much of that for school lunch, so that's why all the meat lol).

I sit down once a week and look at flyers. You don't have to go crazy with every detail, but a general glance even of what's on sale. I make a list of dinner recipes first, trying to use as many of the same ingredients as I can. Frozen veggies on sale can be a major plus because it means mixing it up more in a week. I also buy family pack size meat and break it up into servings and freeze it raw (or sometimes cook up chicken, slice it, freeze, but I prefer to cook from fresh or frozen).

Then try to work out lunches of either left overs, or things that use parts of leftovers. Like a salad, with chicken from last night. Or sandwiches with the roast beef. Or whatever. I don't eat beef so weird example I chose. I also freeze portions of things that I know will taste ok.

Anyway.

I actually like it. I usually do it on my lunch break at work. It's kinda like a puzzle. Adult life. So great. So fun.
