:I take a care bag along with tuna, salmon, cheese and and some nuts. Supplies from the nearest store might include instant oatmeal, almond milk, apples , bananas and a large popcorn , maybe a large lettuce, cauliflower or cabbage.
When we eat out I gently insist on a place where there is a salad bar or where I can fill the plate with vegetables and protein.
Have a good time and be sure to take or buy food that really suits you.
