I agree woth Beth, it's very strange Barbie that there is no temp adjustment. However, I think many of these so called toaster oven/air fryer combos are only wanna be air fryers, but not really. You need temperature adjustment to cook different foods.
Anne: tell me some foods you like and I'll give you ideas. Focus on fatty sources of protein (natural fats bring essential fatty acids which our brains absolutely need !) and fresh grown above ground veggies. If you didn't have a instant read thermometer , get one! It's the key to not over or under cooking meats!
