I really like eggplant but don't cook it nearly enough, so this is a great recipe for me to have available. Add or subtract whatever you want to personalize it, but tomato and vegan :lmayo: is my favorite.
For the eggplant and mushroom, slice them and place in a dish and pour some balsamic vinegar over them. Add some minced garlic on top and leave it to marinade for at least 30 minutes. If you're leaving it for a while you should do so in the fridge.
Once you're ready to cook them, drain the vinegar and place the slices in a single layer on a baking sheet. Use parchment paper, a reusable silicone mat, or some cooking oil to prevent sticking. Set your oven to broil at about 500F and cook for a few minutes on each side. After they cool they're ready to go!
Toast your bread, spread some mayo, add a tomato slice, and that's it.
As a note, I made this with a whole portobello head but I think slicing it and using a couple pieces per sandwich works better.
EDIT: forgot to mention that I stole the recipe from here.
Ooooof yea gotta try this!! I love eggplant, and have recently rediscovered portobello after having gotten tired of it being done badly. This is the recipe that rekindled my enjoyment:

Soooo tasty, especially that butter bean mash! The left over oil is super good to have in too, to just throw onto anything to add some easy flavor
