A smoothie- a few bananas, some peanut butter, some coconut milk and some ice.
Yoghort...with a little honey and some nuts , noodle soup with a little peanut butter mixed in, and some grated cheese,
I actually heat up 1/4 cup of milk. Put three tablespoons of oatmeal or oats in warm milk to soften. And make some frosted flakes, cheerios, chex add 3/4 cups of cold milk to cereal and add your oats!
1 piece whole-wheat toast with jam
A piece of whole wheat toast with some peanut butter on it? A pita pocket with some sliced turkey? I'd try to get some protein in you. good luck and hope your appetite comes back.
