If you don't have a panini press, you can make these easy sandwiches in a nonstick skillet, much like you make grilled cheese sandwiches.
Preheat panini press.
Microwave jelly at HIGH 10 seconds or until it melts. Combine jelly and mustard; spread mixture evenly over 1 side of 4 bread slices. Layer 2 ham slices, 1 cheese slice, and 6 apple slices over mustard mixture on each bread slice; top evenly with remaining bread slices.
Coat sandwiches with cooking spray. Add sandwiches, 2 at a time, to panini press; grill 2 minutes or until toasted.

We loved these! Didn't have apple jelly but apple butter was a great substitute. Easy to make on the George Foreman grill and they were delicious!
