What do I do w/ all these veggies?

So I planned to test a new recipe tonight but after an extremely long day I can barely keep my eyes open. So that is an undertaking that will happen another day. But I glanced in my fridge to see what my options were for dinner and what I found were all the "half vegetables" I used in the gazpacho. If you make the gazpacho, you are left with:

-Half a green bell pepper

-Half a red onion

-Half a cucumber

-And (probably) a whole bag of celery (because only 2 ribs were used)

Not to mention the parsley, garlic, and a bottle each of olive oil and vinegar that you may or may not have had in your kitchen anyway. So what to make? I'm thinking I might use the oil and vinegar to make a marinade for the veggies and then throw them on a salad.

So stay tuned for an easy "round 2" recipe to ensure these veggies don't go to waste. Also, feel free to comment with suggestions for what YOU would do with these vegetables! I know that alot of my friends and family reading this cook just as much, if not more, than me!
