Not exactly meal ideas, but some things to help....
Eggs - not just for breakfast, boiled and cut up to add to a salad or just eat as a snack, an omelette for any meal, egg salad
Boneless skinless chicken breast - it's always on sale in our area for $1.89/lb. There's very little waste. There are tons of ways to cook it. Grill it up, have it for dinner, used leftovers to cut up and add to a salad, or make a sandwich . Make a chicken stir fry. Use the chicken to make chicken fajitas.
Carrots - less than $1/lb for organic. Keep carrot sticks on hand for snacks, or steam for a side dish. Add to a pasta salad, a tuna macaroni salad, soup or stew.
Pork loin - just like boneless chick there's very little waste. A large pork loin is always on sale for $1.99/lb. - make a roast, or cut up into pork chops - very good cooked on the grill.
Pasta -
Waffles or pancakes - have breakfast for dinner. For a special fun meal, fruit is in season, rather than syrup, top the waffle with some icecream and fresh berries.
Stir fry - use whatever is on sale and what you have on hand.
Fresh veggies are in season and there's bargins to be found. We went to the flea market this morning, mostly for something to do. For $5 - 3 med green peppers (that had a few minor sun burn spots), 3 med cucumbers, 3 small zucchinni, 3 large eggplant.
