Nutritionally dense dishes are those that include a large amount of energy and nutrients in a very small volume.
You can prepare chicken or cod croquettes; empanadas (meat, tuna, egg, cheese, etc.), which can be frozen and fried or warmed up; nutritious pâtés to spread on toast or sandwiches; energy purées and soups, which can be kept in the fridge and consumed directly (hot or cold), and finally, sweet preparations, such as a dessert or to snack on in between meals, such as caramel puddings, Greek-type yoghurts, and many others.
Prepare complete smoothies with fresh fruit, dairy or plant milk, nuts, dried fruit, biscuits…
Dishes can also be enriched in order to increase their nutritional density with high-energy and/or protein-rich foods:
Soups and purées: add grated cheese, powdered milk, hard-boiled egg, diced serrano ham, chicken, or fish.
Salads, pasta, rice, vegetables, and other dishes: enrich them with cheese, mayonnaise, tuna, egg whites, fresh fruit, diced Serrano ham, etc.
Milk: powdered milk, cocoa, honey.
Yoghurt: add fresh fruit, syrup or compote fruit, dried fruit, honey, breakfast cereals, and jam.
