It's just DH and myself. We're spending about $600+ on groceries. We do eat all three meals at home, every day, but I feel like we're getting robbed. We try to eat healthy meals all day, new recipes nightly. Last week we made pulled pork, eat this/not that enchiladas, sausage and peppers, shrimp pepperoncini, eat this/not that philly cheesesteaks, stuffed peppers. and chicken marsala. How do we lower our costs?
Well, at $600 a month, divide that by 30 days in a month, then divide again by 3 meals a day, then by 2 for two people, and that's only 3.33 per meal per person on average, that's not
that bad. But there are some ways to cut that down. As others have said, you can cut your meat consumption to save some money. Also cheese is expensive, if you cut back/out on cheese that could save some $$$ as well. Also for cheese, if you buy pre-shreded, start buying it in blocks and shred your own, it's usually cheaper (and I find pre-shreded dosen't melt as well).
Getting back to meat, I find roasting a whole chicken to be a good way to go. I marinate it in home made itailian dressing overnight, then roast it and get two meals plus enough for one or two chicken salad sandwiches out of it. The chicken costs $5 and the dressing marinade is made from what I have on hand in my pantry/fridge.
Pizza dough is easy and cheap to make from scratch (especially if you own a stand mixer, no hand kneeding needed!) and makes a great meatless meal as well.
If you have the space and inclination, you can try growing some of your own veggies to cut down on produce costs in the summer/fall (and even winter if you can freeze/can some of it). If you can't/don't want to do that, look for farmer's markets in your area. They may be cheaper, and the quality is usually much better.
For breakfast, if you eat cold boxed cereal, switch to steel cut oatmeal, it's cheaper and better for you. I add flavor by putting in dried fruit (usually apples) and adding a sprinkly of cinnamon and a drizzle of honey. Yum!!! I make it in my lil' dipper crock pot overnight (just enough for me) so the dried apples get nice and soft, but if you want to make it for two you can do it in a small crockpot too.
Just for reference, DH and I spend about $400 to $500 a month on groceries (depend on how much wine we buy....) for the two of us, so you aren't that far out of wack. With a bit of tweeking you should be able to get it down some.
