Meat comes in tins at Wally, high sodium but can be significantly reduced by soaking in water for a bit prior to use and drain. Chicken, tuna, pork and beef, and comparable in price to fresh. Great for those on a budget. Add it to rice, beans, potato, with canned veggies, compete meal. Canned veggies at Wally are down to 40¢ a tin, bargain. Peas, carrots, string beans and corn.
Dollar General has the flaked, chunk ham for a dollar which is hard to find at that price.
Dollar tree specials are the canned mackerel, 15oz for a dollar. Pain to clean, but tasty fried with seasoned breading mix in a little Olive oil.
Their frozen section now has pork chops, rib eye, etc... in convenient single size portions. You can get four meals if you do it right, eating them the next meals after purchase.
Lunch and dinner easily the same day purchased. If you keep the Frozen meat in a cool place, since it's sealed, can cook it the next day and still be fine. Great for next meals right after picking up supplies. And if you pick up some fresh veggies, they as well should last 2-3 days for salads and side dishes.
The roasted chicken from Wally are also great for a couple meals. One meal right away, second or third in salads, rice, sandwiches. Strip the meat asap and place in ziplock bags, will keep another day if stored in a cool place.
Hit Wally at the end of the day or early morning and often pickup the chicken and other deli meats for reduced price, sometimes even half, depending on the store. The ranch chicken wings at half price are the major score. Yummy.
Ways to add variety to your PB, Mayo and condiments. Btw, jam can keep as well for a week or two if stored in a cool place. Buy a small container and use it up daily as a treat or dessert. No fridge or ice required.
Obviously this doesn't hold true if you are parked in the sun at 90+ heat and your van is at 110+ heat inside.
Bon appetit!
