Nobody is going with Chinese Buffet yet? Kidding...
A bagel a protein source, usually. Bagels just work really well for me. Outside of that, sometimes something fun and sugary like Pop Tarts or kid's cereal. Usually enough of whatever it is to give me about 30-50g carbs. Those three are favorites for my full refeeds, too. They fill me out, no bloat, no gas, no nothing. I just look and feel amazing the next morning.
