In school I have a club called Writer's Club and last time I brought edible cooki dough. We normally have cookies and juice boxes so what would be a good idea to bring to a meeting?

Our oven broke and now all I have to use is a toaster oven.

Why not just continue with cookies, brownies, etc? Or add granola bars, yogurt, trail mix and throw in some chocolate chips, Chex mix, chips and dips, crackers and cheese. Some of those are expensive of course.
You could make tea, cocoa, and coffee if it's cold out.
Lemonade and ginger snaps is an early American tradition.
My once in a blue moon snackable that's a meal in one is Greek spanikopita, little filo dough spinach rolls. Polish pierogies. Pita bread pinwheel rollups filled with salmon and neufchatel. Now I'm getting carried away.

Or samosas? In Girl Scouts, we made little sandwiches out of layered bread containing cheese and meat fillings, like this How to Make Beautiful Finger Sandwiches | eHow.com. You can keep it simple, or you can get wild and crazy with fillings. I'd buy some meats and cheeses at the deli and use rye and wheat and white breads to make sandwiches that I would cut into triangles.

Thanks
