Preparation

• While preparing the ingredients, bring 4 qt. water to a boil over medium-high heat in a large pot; add 2 Tbs. salt and the pasta to the boiling water. Cook the pasta, stirring frequently, until it starts to soften, about 7 minutes, and then add the asparagus.
• When the pasta and the asparagus are tender, add the peas and spinach. Stir and simmer until the spinach is wilted, about 30 seconds. Reserve 1/2 cup of the pasta water and then drain the pasta and vegetables.
• 同时，在10英寸的煎锅中加热大蒜和油，直到大蒜开始嘶嘶声并变成金色。添加西红柿;煮至足够厚的涂层意大利面，4到5分钟。加上奶油;继续烹饪，直到酱汁再次厚，足以涂上面食，2至3分钟。
• After draining the pasta and vegetables, return them to the pot and add the creamy tomato sauce, the reserved pasta cooking liquid if necessary, the Parmesan, and chile flakes; toss to coat. Taste and adjust the seasonings. Serve, passing the additional cheese separately.
