How to Make It
Cook pasta in boiling salted water until al dente, about 10 minutes, or as label directs; add broccoli for final 3 minutes. Drain, reserving 1 cup cooking liquid. Toss pasta and broccoli with 1 Tbsp. oil.
Warm remaining oil in a skillet over medium-high heat. Add chicken, onion and garlic, sprinkle with salt and pepper; sauté for 5 minutes. Add tomatoes; sauté for 2 minutes. Toss in pasta, broccoli, Parmesan and 1/2 cup of cooking liquid. Add more liquid if dry.
