Half a small apple with a thin spread of peanut butter. Easy calories and a little protein when nothing else appeals.
Eat slowly — one slice at a time. If the peanut butter feels too heavy, scrape most of it off and just have the apple.
Granny Smith apples work well if you prefer tart over sweet. The slight sourness can help with nausea.
Swap peanut butter for sunflower seed butter for nut-free. Use any apple variety you like.
