I would suggest getting one of the pre made graham cracker crust from the store. Then use this
cheesecake sub the cherry for apple. I have made the apple one many times for lots of people and its really good. Simple to make!
For Stuffed peppers I would suggest sausage stuffed peppers. You can use turkey sausage and brown rice in them.
Like wise if you need more cheesecake option let me know. I have a ton. They are not really low cal though, but I would think you could sub artificial sugar for the real thing.
