For years we have been trying to figure out how to get the most calories in the smallest amount of food as possible. Lean Cuisine's, have a good amt of calories and a good size just for a snack. Anna' used to eat two glazed chicken Lean Cuisine's for a snack after school around 4pm then still eat supper at 7. Trying more frequent small meals/snacks. We have a recipe for alfredo sauce that is really good and is packed with calories if you want me to send it to you. It's completely from scratch though. Ben and Jerry's ice cream is also loaded w/calories. Someone else mentioned pastas, which is good. Chef boy ardee. I'm thinking college student quick meal/snack here. Then the usual, butter, whole milk, heavy cream.
