Yes indeed, I forgot to mention smoothies! You can really make them tasty & with plenty of calories. I used full-fat greek yogurt instead of cream, even added protein powder & veggies like carrots and avocado. When my throat hurt, it was soothing too.
Now that my weight is stable, I don't "load" them with calories, my grands will drink them too if we pretend they are adult food that they can only have as a special treat.
Think I'll make a pitcher today - we have a refrigerator full of quite ripe fruit & berries!
