It’s hard to top the perfect slice of pizza. (And we’re not talking green peppers and onions.)

But organic pizzeria Slice has figured out a way. Its new Build-Your-Own Pizza Kits can be used to raise big money for the school or organization of your child’s choosing.

This fundraiser of the future (bye-bye bake sale) is easy to implement. You pay $5.99 for a kit, sell it for $9.99, and end up with a healthy profit.

And in a further gesture of goodwill, if your child’s school does regular pizza parties, Slice will donate a party to a less fortunate school.

And that’s wholesome any way you slice it.
