Fabio says you should put a fried egg on your sandwiches. He does so in his video The Perfect Late Night Sandwich.
I tried this sandwich, modified for kashrus. Here is what I did.
1. Drizzled olive oil on bread, and toasted it in a grill pan on one side.
2. Fried an egg. (actually, I fried 3)
3. Make a sandwich with the bread, toasted side in. Put in the fried egg, and deli sliced turkey. And put on hot sauce.
It was some mean sandwich. You should make it. Tonight. For dinner. And then post here. Have a homebrewed beer with it. And maybe a home pickled pickle.
