I’ve enjoyed ham and cheese on a mazoh, but they’re better with peanut butter or nutella.
My college dining hall offered sandwiches on matzo during Passover, presumably for Jewish students keeping kosher for Passover. A Jewish friend of mine ordered a ham and cheese sandwich on matzo- the dining hall people didn’t even bat an eye. 
Imagine this breakfast sandwich:
Toasted bagel
scrambled eggs
ham
slice of cheddar
Grape Nuts cereal
pork floss (or pork foo or moo yong if anyone speaks Thai )
toasted bagel
It was bliss, I tells ya! But the boyfriend has always brought that up to show other people how I eat foods that don’t go together. What!? Pork floss is pig. Ham is pig. I see no difference! And the cereal made it crunchy - it’s not wrong! Mmm…
My college girlfriend admitted that as a kid, she would make herself “pizza” in the toaster oven using Wonder Bread, ketchup, and a slice of processed American cheese.
That, my friends, is ethnic food abuse.
Emergency food!!! My PBJB (Peanut Butter and Jelly Burrito) is my regular breakfast!! My only big decision is which kind of jelly to use …
Before my days as a vegetarian, my favorite sandwich was a toasted salt bagel with butter and bacon. I still have one with soy bacon on occasion, but it’s not the same.
There’s a restaurant in Ocean City MD, called the Bayside Skillet where you can get crepes with any kind of filling imaginable. One favorite is PB&J crepes. The crepes are filled with the jelly of your choice and then peanut butter is spread over the top of the hot crepes, so it gets all soft and melty. Yum.
I’ve never done PBJ in a tortilla, but a slice of American cheese and a chapati rolled into a cigar is delicious. 
Leftovers + tortilla = lunch. Chicken, pork chops, steak…whatever. Slice it/chop it & roll it into a tortilla & heat.
Somehow talking about ham on matzoh and bacon on bagels just seems wrong…
It may be wrong, but my, they taste goooood.
OK, so now I’ve been thinking about a PBJ tortilla for about two days, and I finally broke and tried it. YUM!
You people are a bad influence.
Come over to the Dark Side, Scarlett. We have PB&J tortillas.
And cookies! 
Why, that’s the nicest thing anyone’s said to me all week. Thank you.
