Throw a bit on the charcoal right before putting the meat on the grill and let the smoke flavor it. Works with garlic tops too.

Guess it depends on what you like to eat. Personally I can find lots of uses for them fresh and dried. Salads, steamed as a side dish, lightly fried as a side dish, grilled, diced on top of fresh tomatoes, on baked potatoes, great on a hamburger either fresh or grilled, any thing you would use chives in, scallion pesto, in scrambled eggs, in spaghetti sauce, diced into meatloaf, as a taco burrito topping, etc.

Check out all the posts about them over on the Alliums Forum here. The search there pulls up lots of discussions on growing and using them. And you can find cooking recipes for them over on the Cooking forums here not to mention Google using 'scallion recipes'.
