Pasta E Fagioli (pasta and Beans)

If using dried beans, rinse them and pick them over and then rehydrate and cook them; drain and set aside. If using canned beans, drain them and then rinse and drain well again; set aside. In a soup kettle, bring the water to a boil. Add the pasta and the 1-tablespoons salt. Stir and continue to cook over high heat until the water returns to a boil, stirring frequently. When the pasta is half-cooked (about 6 minutes), add the drained beans to the pasta pot. While the pasta and beans are cooking together, in a skillet over medium heat, warm the oil. Add the rosemary and onion and saute until lightly browned, about 10 minutes. When the pasta is al dente (tender but quite firm to the bite), drain it, and, while it is still dripping, transfer to a warmed serving bowl. Add the browned onion and toss well. Sprinkle liberally with pepper to taste, and add more salt if desired. Serve at once. Serves 4.
