Day 23: Veggie Sub With A Fried Egg

Veggie sub with a fried egg

This veggie sub with a fried egg has a savory element from the caramelized onion and cheese and a crisp bite from the cucumber and sweet peppers. It’s also a little messy, but very delicious, so it’s totally worth it.

Veggie Sub With A Fried Egg

Recipe by Dee


  • 1/2 of a sweet onion, cut into 1/4 inch slices

  • Thinly sliced extra sharp cheddar cheese

  • 3 snack peppers cut into 1/4 inch slices

  • 1 small cucumber cut into thin slices at an angle

  • 1 large egg (optional)

  • 1 hoagie roll

  • Unsalted butter, softened

  • Fine sea salt


  • Place an 8 inch cast iron skillet over medium-low heat. Once it is hot, add 1/2 tablespoon of butter to the pan and once it has melted, add the sliced sweet onion and a pinch of salt. Cook for 15 to 20 minutes, stirring every few minutes, or until the onions have browned and taste sweet. Remove the onions from the pan.
  • Turn on your broiler and set to low. Cut the hoagie roll in half and add the caramelized onions and cheese to the bottom half of the bun and spread butter on the top half of the bun. Place the buns on a pan and set about 4 inches below your broiler. Broil for 3 to 5 minutes or until the cheese has melted and the top half of the bun has browned. Remove from the heat.
  • While the sandwich is broiling, place the 8 inch skillet back over medium heat and add 1/2 tablespoon of butter. Once the butter has melted, crack the egg and add it to the pan. Cook until the white has set and the yolk is cooked to your liking. Sprinkle with salt, then remove the egg from the pan and set aside.
  • Remove the sandwich from the oven and top with the cucumber, peppers, and fried egg. Add the top half of the bun and squish down so that the sandwich does not fall apart the moment you pick it up. Enjoy!

Try this apple bacon tuna salad one instead! (Or you could try them both!)


  • This sandwich is delicious with and without the egg. Try it both ways and see which one you prefer.
  • My go to cheese is extra sharp white cheddar, but you can use whichever melty cheese you like. 
  • Keep a close eye on your sandwich while it’s in the broiler to ensure it doesn’t burn.
  • It may take more than 15 to 20 minutes to caramelize the onions, but it depends on the burner you use. The burners at the front of my stove are very hot so they tend to cook things quickly.

Ramblings: Have I talked about this before?

I honestly don’t remember if I’ve ever rambled about veggie sandwiches before.

I know I’ve wanted to but…

Wait a second, yes I have! I made that spaghetti squash sandwich last year.


In any case, veggie sandwiches, like this veggie sub with a fried egg, are so much more delicious than I would have thought when I was growing up.

Granted, I had a lot of veggie related reservations when I was a kid, so that’s not too surprising. 

And I know that the egg takes away from the full veggie-ness of this sandwich but it is optional, so you can nix it if you want.

(I know I call these little chats at the end rambles, but I think this one has to be one of the most rambling ones so far.)

The end!
