pre-op changes

Surgery is at the end of August...I have a list of habits I'm supposed to work on, including 3 meals a day (actually one of those meals is a protein shake) plus a couple of 100-ish calorie snacks. Must contain protein. Suggestions on the snack part? What are your favorites? 

Triple zero yogurt although it's 160 cals it is 15 g of protein. Also, cottage cheese, ****tail shrimp, cheddar cheese stick are usual go-to snacks for me. 

Hard boiled eggs, babybel cheese or cheese sticks. Cheese and pepperoni (turkey if you want), Jerky, Greek yogurt

Shrimp and ****tail sauce, tuna pouches, turkey and cheese roll-up... leftovers...
