All entrees that are a single serving are eligible. You could not order a whole pizza for one credit. Know that when you are at the resort, you can use your refillable mug and get an eligible snack credit item for your drink. (I get coffee, using my mug, and pick up a pastry from the bakery - in addition to a bounty platter and we share. It's plenty of food for us - and we then have a credit for a shareable lunch).
