Pasta Salad

About 1 1/2 pounds ripe tomatoes, halved or quartered if small, diced if large
sausage or 2 cans olive oil-packed tuna or 1 pound mozzarella cheese, diced (optional)
2/3 cup pitted oil-cured black olives, halved, or 1/2 cup pitted green olives, chopped, or 3 tablespoons capers (optional)
2/3 cup chopped fresh herbs (basil, parsley, mint, chives, cilantro, scallion tops, or a combination), more for garnish
zest of 1 lemon (optional)
3/4 cup extra virgin olive oil
black pepper
2 pounds short pasta, like fusilli, farfalle or penne
Hot red pepper flakes (optional)
1/2 cup toasted pine nuts (optional)

Up to 4 hours before serving, put tomatoes in a large bowl and sprinkle all over with salt. Set aside for 30 minutes, then drain off liquid.

Add tuna and its oil, olives or capers, if using. Add herbs and zest. Add olive oil, salt and pepper to taste and stir gently, flaking tuna into pieces. Cover and set aside at least 1 hour or up to 3 hours, stirring occasionally.

Cook pasta in plenty of boiling salted water. Drain very well. Combine tomatoes and pasta well, then taste and add more oil, salt and pepper to taste. Add red pepper flakes if desired. Sprinkle with pine nuts, if using, and chopped herbs. Serve immediately.
