I did these for a little snack and they were fantastic! I just broiled these until my liking.
- deli sliced pepperoni
- spreadable cream cheese
- low sodium mozzarella cheese 
- everything but the bagel seasoning
- and I like a little spice, so I added a pickled jalapeño to them.
Just spread on a thin layer of cream cheese, a dash of shredded mozzarella cheese, sprinkled the seasoning on, broiled in oven for just a few, and done!
