This was a pretty pasta salad for our Kentucky Derby party this year.  Colorful and it had a lot of flavor.  And of course pasta salad is always great for a crowd.

• 1 box rotini pasta, cooked to al dente and drained (tri color especially fun)
• 8 oz grape or cherry tomatoes, halved – heirlooms would also be nice
• 8 oz package Mozzarella pearls
• 1/2 cup fresh chopped basil
• 1/4 cup pesto 
• 2 tablespoons olive oil
• 1 tablespoons balsamic vinegar
• Salt and pepper, to taste

Combine all ingredients and toss well.  Chill for at least four hours until
