Pasta with Peppers, Squash, and Tomatoes

• coarse salt
• 3/4 lb rigatoni
• 2 tbl extra-virgin olive oil
• 1 lb sweet or spicy Italian sausage, casings removed
• 1 bell pepper (not green), cut into 1/4-inch strips
• 1 small yellow/summer squash, cut into 1/4-inch rounds
• 2 lb cherry tomatoes, halved
• red-pepper flakes
• grated Pecorino Romano, for serving

1. In a large pot of boiling salted water, cook pasta according to package instructions. Reserve 1/2 cup pasta water, then drain.

2. Meanwhile, in a large skillet, heat 1 tablespoon oil over medium-high. Add sausage and cook, breaking apart with a slotted spoon, until cooked through, about 6 minutes. With slotted spoon, transfer sausage to a bowland set aside.

3. In the same large skillet, add 1 tablespoon oil and bell pepper to skillet and cook, stirring occasionally, until browned in spots, 6 minutes. Add squash and half the tomatoes; cook 1 minute. Add 1/4 cup pasta water and cook until tomatoes soften, 4 minutes. Return sausage to pan and add remaining tomatoes.

4. Season with red-pepper flakes. Cook until sausage is warmed through and juices thicken slightly, about 2 minutes. Toss with pasta; if necessary, add remaining pasta water to create a light sauce that coats pasta. Serve with Pecorino Romano.
