School Fundraising EVENT for charity?

How about selling soft pretzels? Most people I know love them. At my school we were able to raise money for prom by selling them from 1-3 times a week during lunch time, which I think is the best time to sell them since a lot of people don't like school lunch. 2 pretzels for a dollar and one for .75 cents is how much they cost for us, just an idea of how much you would want people to spend. They would also have mustard and brown bags for them if they needed one. I'm not sure how much we made from it but I know we made a lot from it since our prom tickets only costed 50 where as other high schools have to pay up to a 100 just for one ticket. Good luck!
