I'm looking for healthy and affordable meals that don't require too much cooking.  It's starting to get hot here and I can't afford to run my air conditioner since I lost my job.  We have a grill but nobody is interested in hot food.  Also I have one allergic to pork and one can't eat cheese and similarly processed dairy.  My son won't eat soups either says it makes him sick.  Maybe I should have posted this under picky eaters, btw my son is 15 and I have 2 daughters 18 & 20.  So there are not young picky eaters, just picky eaters that are vocal about it.   Two go off to college in the fall and that leaves me dealing with no soup and pork allergy at that time, but for now I have to deal will all of it and still have something on the table for them to eat.
Does anyone have ideas for healthy cost little meals?

Sometimes in this weather the best thing to look at is salads. They can be stretched to feed alot of people and can have many things added to them (or things left out of them for the "picky" ones). If you want to make a Mexican type salad make a base using lettuce, sweet peppers, black beans (in place of any meat), and tomatoes. You can then put things like shredded cheese, jajapenos, carrots, radishes, cucumbers, etc etc. Make a dressing using lime juice, chili powder, and cumin for the flavour of the south. This idea can be put to many different salads - Italian - use roasted red peppers, add pepperoni or salami, make the dressing using lemon juice and thyme; French - use hard boiled eggs, green beans, black olives, canned tuna, make the dressing using lemon juice, thyme, olive oil (kind of a Nicoise type of salad). There are alot of different lettuces you can use, and many different types of dressings. You can stretch the meals by adding different breads - whole grain baguettes, rye, focaccia. I find that making my own salad dressings is more cost effective than buying the bottles and then I know exactly what is in them. Hope this will help you.

That salads suggestion is excellent, and I'd just like to add a suggestion or two to it.

If your grill has a cover, you can use it to cook just about any meat you'd normally cook in the oven. So you can still have your meat without heating up the kitchen. Just preheat the grill, keep the temperature fairly low and watch the meat to see when it's done. Then you can have chicken, turkey parts, roast beef or whatever to cut up in your salads or to serve beside it.

Using them cut up in the salad, you save money by not using as much meat per serving, and you can freeze the leftovers in portions to use within the next few weeks. Don't buy meats unless they're on a special sale, but when they are if you have the freezer space buy two of them. Then you shouldn't have to buy any of that type until they go on sale again. Do the same with cheese -- buy two packages when they're on sale instead of one. And with eggs -- hard-cooked eggs are very nutritious and can be used in many ways. Buy several dozen of them, at least, when they're on special. Eggs can be kept refrigerated for weeks.
