Place eggplant halves cut-side-up in a roasting pan
Brush with 2 tbsp of olive oil
sprinkle with salt
Roast for 15-20 minutes
Let cool slightly
Place in a food processor along with the balsamic vinegar, garlic, the rest of the olive oil, and pepper
Blend until smooth
Adjust seasoning
To Make the Sandwiches
Place cheese on 2 slices of bread top with 2 tablespoons of the eggplant caviar per sandwich
Add the top slices of bread. Pro tip: I like to add a extra cheese on top of the eggplant so the top slice of bread sticks better. (And of course it's cheesier too!)
Heat up your Panini press (or George Foreman grill)
Add panini one at a time, and grill until cheese is melted
Notes
If you don't have a panini press or grill, a frying pan with butter will work. I've found that the George Forman Grill is an easy way to make grilled cheese sandwiches with almost no mess and no burning!
Nutritional Information
The numbers below are for the entire batch of eggplant caviar. Your sandwich only takes 4 tablespoons out of the batch.
