greek salad is always a fave...and some stores have yummy (kosher l'pesach) baba ganoush, which is always great on matzo. Also, many people don't know this but quinoa is kosher for pesach (but if you don't have a pot to cook it in, that's a problem). There might be a way to make quinoa in the microwave but I"m not sure. Also, if you put aluminum foil over the broiler in your oven so that it is kosher, you can make matzo pizza with cheese, tomatoes, artichokes, other yummy things.
