Pesach Questions

Looks like I will have an extra half a loaf of bread, frozen pizza... Can you recommend a place to donate such items or another good solution (versus throwing out)?

SOVA is a great resource to donate to.  https://www.jfsla.org/page.aspx?pid=300 

It may be hard to find a place that accepts food that has already been opened. If you can freeze it and sell it with your chametz, give it to a non-Jewish friend or colleague, etc that might be best.
