LOTS LOTS LOTS you can do with green peppers...here are some of my faves.
1.  Chop and freeze in plastic containers.  Fork out a few and use in scrambled eggs in the morning.  (you can do the same with onions).
2.  Make Spanish arroz con pollo.  Make sure to use the short-grain sushi rice (don't use long grain!!!) and real saffron, or it won't turn out very well.  Each recipe uses 2 green peppers (it says 1 red and 1 green here but you can use 2 green). 
Here's a good recipe--but note--I leave out the chili peppers.  This is not a traditional recipe--this dish is NOT spicy!  Use a little glass jar of sweet pimientos instead.  Also--add 1/2 cup of dry white wine in with the water for a great flavor.  Garnish with lemon juice or fresh lemons when serving.
