It's kind of tough because I have a pretty small sleeve despite my surgeon using a 40f bougie, I'm a vegetarian and I'm in maintenance (which means I eat many more calories and many more carbs than I did during the loss phase.
I get most of my protein from shakes, most of my fats from nuts and fill in around with fresh or roasted veggies and berries, apples, pears or oranges. I also eat a bowl of plain steel cut oats with cinnamon most days because I have fallen in love with them.
I avoided the fruits and the oats during loss.
I eat almost no white carbs (processed sugar, breads, potatoes, rice, crackers, etc.) with the exception of a planned sweet dessert once a week. My feeling is in maintenance it's easier to be good most of the time if you plan a treat now and then. However it's important to notice if something is causing too much temptation. For me, that's crackers and chips. Crackers are my crack so I never, ever, ever eat them.
I eat about 6 'meals' a day on regular days, 7 or 8 when I'm hiking. I count my protein shakes as a meal in that context. When I'm hiking I drag along a homemade healthy granola trail mix with nuts and raisins and oats baked with a teeny bit of honey.
