I just bought a Nesco FD-61 and am giving my first go with a very small batch of tomatoes and peppers. I ended up cutting the stems off the habs, but leaving them whole. I cut the jalapeno in half. For the tomato, I wasn't sure what to do since it was a large tomato. I ended up just slicing it like I normally would for sandwiches and then cutting that in half.
Any other suggestions?
