Take plain rice and add a (dry) package of vegetable soup to it! Knorr is my favorite. Dried veggie flakes are good in rice too.
Egg noodles, cooked and then tossed with some sauteed mushrooms and fresh green onions and pepper.
Grill or panfry a plate of thick sliced peppers and onions and fresh garlic.
A nice tzatziki (grated cucumbers, plain yogurt, sour cream, onion, salt and lotsa dill) with pita bread would be nice too.
Or a nice cold rice and bean salad with a light vinegarette would be good!
I also like to take little new potatoes, slice them in several slices, put on a piece of tinfoil, drizzle with olive oil, season to taste (I like the Greek seasoning or Mrs. Dash on these) wrap well in foil and roast in oven or on the bbq. If they are smaller, they won't take very long to cook.
