Ham slices (thin sliced works best, especially for little munchers but I didn’t have thin so I cut mine into slivers so they wouldn’t pull an entire slice out with the first bite) on a slice of wheat bread with thin apple slices (our were Gala, tart apples work really well too) and cheddar cheese on top. You can see from the picture that I got a little fancy with my cheese, hey, sometimes with this crew it really does come down to presentation! I also like a little honey mustard on mine under the ham (just a little, though, or when it gets melty the ham will slide right off the sandwich!).
I put them in the oven at 400 for about 15 minutes until the cheese was melting. I had to switch to broil for a minute because the troops were getting restless but the apples were still a bit crunchy because of that (still tasty though). The reviews were mixed. My girls dissect all their sandwiches, even pb&j so, as expected they pulled these apart too. Twinkles at ALL of hers, Pinky ate most of hers. Punkin announced that next time I make these he’d like his without apples but he did appreciate the checkerboard cheese so I guess I’ll call it a win!
