The simplicity of this healthy pasta recipe makes it good family fare. For a touch of heat, mild Anaheim chiles are augmented with crushed red pepper and garlic.
Combine red and yellow tomatoes with salt in a large bowl. Let stand, stirring occasionally, until the tomatoes soften and release their juices, about 40 minutes.
Bring a large pot of water to a boil over high heat. Add pasta and cook according to package directions. Drain and rinse with cold water.
Dry the pot and add oil; heat over medium heat. Add shallots and garlic; cook, stirring occasionally, until the shallots soften, 3 to 4 minutes. Add crushed tomatoes and their juice; bring to a simmer. Cook for 5 minutes. Add the pasta, the fresh tomatoes, chiles, arugula, oregano, crushed red pepper and ground pepper. Cook, stirring, until hot, about 2 minutes. Serve topped with Parmesan, if desired.
