Favorite Things About Summer...

As the weather in New York SLOWLY transitions into something resembling Spring/Summer, I have been trying to think of recipes and drinks that remind me of this great time of year.

This previous weekend my roommates and I hosted a "Dos de Mayo" party, which was a big success. There we had beer margaritas and they were delicious! 

So my question to you dear foodies is, when you think of Summer what are the "must-have" recipes that come to mind?
