I like ham in mine at well. The sandwich maker/toasters were very popular about 15 - 20 years ago they went out a bit but have made a comeback recently - I do have one but rarely use it.
You have given me taste for doing one tomorrow.
Yes, the sandwich grills were out of favor here for awhile, too. We had a lot of years where people thought bread was bad. (I never gave up on it!)
Anyway, we used to grill ham salad (or bologna salad) sandwiches, cheese sandwiches, tuna sandwiches.
Hope you enjoy one soon!
