I don't think any one said this yet....
A great way to keep the grocery bill down is to ONLY buy what is on sale. You have to use the weekly flyers to make your meal plan for the week. You also have to have a small amount of grocery money held in reserve for the times that something your family eats a lot is deeply discounted so that you can stock up.
Use coupons.....there are plenty to be found online.
I have a friend that spends $200/week on groceries....they are a family of 2 adults and 2 kids age 2 and 7. My family only spends $60-$80 per week on groceries...we are a family of 4 adults. The difference? I only buy what is on sale.
BTW...I envy all of you that say you can get chicken breast for $2/lb. Where I live it's $6-7/lb and the rare occasion that it goes on sale it's $4/lb. Also, milk....here it's between $4 and $7 for the equivalent of a gallon.
I second the suggestion to find and Aldis and shop there.
One more I just thought of.. I just bought two pork roasts from our local Aldi for 1.49/lb. They were about 2 1/2 lbs each. This recipe is awesome, but you need to find some smoked salt. I bought a jar of it at Home Goods for a couple of dollars and it has lasted me for a few years.
Slow-Cooker Kalua Pork
2 1/2 to 3 1/2 lb boneless pork shoulder roast
1 Tablespoon smoked salt
Rub salt into roast. Place in slow cooker and cook on low 8-10 hours or until meat shreds easily with a fork. That's it!
You can eat this on a sandwich like pulled pork, or use it in fajitas. Have it plain with mashed potatoes or macaroni salad. When I make it it usually feeds us for three meals. (Four of us - two kids are away at school.)
I also go to Costco and buy there already made chickens. I pull the meat, make pot pies, fajitas, empanadas, and you can take the carcass to make stock or soup.
I do this too! The homemade stock tastes so much better is is much less expensive. I freeze it in mason jars.
I also freeze the pulled meat in meal size servings to use in casseroles, etc. That rotisserie meat makes a casserole taste sooooooo much better!!
One of my favorite meals on the cheap is comfort food for me, Creamed Tuna and Peas over Toast, but I know it sounds gross to some so skip it if you wantI use the Hillbilly Housewife recipe (not sure if I am allowed to link to it or not but you could just Google search it)
Actually, if you haven't checked out the Hillbilly housewife website before- she has great, fugal meals!
