You will need:
4-5 big juicy tomatoes (I like 2-3 different colors)
a bunch of fresh basil
half a block of feta cheese
a good handful of freshly shredded parmesan
2 garlic cloves
Dice up the tomatoes, quite small. Chop the basil, brake up or chop the feta cheese, mince your garlic. Combine all of it in a big bowl. Drizzle olive oil over the top and generously drizzle the vinegar over the top. Salt to taste. We just eat it with blue corn tortilla chips, but it's also amazing on some broiled baguette or just bread.
I think Trader Joes hat THE BEST balsamic vinegar. It makes this entire dish.
