Well, my favorite sandwich is the one sitting on a plate in front of me.
If it's not there yet, I like to make:
1. PB and banana
2. PB and iceberg lettuce
3. Virginia ham and swiss with coleslaw
4. Any reuben, but especially knockwurst
5. My own tuna salad (heavy on the chopped sweet gerkins)
6. Egg salad
7. Cream cheese and olives
8. Meatloaf with French's mustard
9. Omelet on a hard roll
10. Homegrown tomato with american cheese and mayo
I could go on, but I've suddenly gotten hungry for some unknown reason. I think I'll go make a sandwich.
