Weeknights will be a breeze when you follow Sarah Newman's method for preparing this easy shrimp supper. From Brooklyn Center, Minnesota, she writes, “I saute the garlic and onion in the morning and add the tomatoes. I also stir together the milk, flour and half and half and put both mixtures in the refrigerator. When it's close to dinner time, I just cook the pasta and shrimp and put the few remaining ingredients together, and dinner is served!".
