Cook Pasta & Green Beans: Boil 10 ounces short pasta in salted water until almost al dente. Add 6 ounces green beans halfway through. Reserve 1 cup pasta water, then drain and rinse briefly to stop cooking.
Make the Pesto Sauce: In a large bowl, mix ½ cup pesto with a splash of pasta water until creamy and glossy. Adjust with more water if needed.
Toss & Serve: Add pasta, green beans, ½ cup olives, 1½ cups cherry tomatoes, and 2 handfuls arugula. Toss gently, adding more pasta water or olive oil if dry. Top with 2 tablespoons pinenuts and serve right away or keep refrigerated.

Tips
Cook pasta al dente so it stays firm in the salad.
Save pasta water to make the pesto creamy and clingy.
Rinse with cool water to stop cooking and keep veggies crisp.
Chill before serving for deeper flavor and a refreshing bite.
Use fresh herbs like basil, parsley, or arugula for brightness.
Mix gently so pasta keeps its shape and pesto spreads evenly.
Add protein with chickpeas, beans, or grilled tofu.
Toast your nuts for crunch and a nutty boost.
Storage
Store leftovers in an airtight container in the fridge for up to 3 days, but avoid freezing as the pasta and veggies lose their texture.
