GFCF Eggplant "Lasagna"

Eggplant has been on sale recently. Inspired by the success of Spaghetti Squash Lasagna, I bought an eggplant and decided to make lasagna out of it, too. Predictably, the girls won't go near this, but DH and a friend thought it was great!1 medium eggplant, washedsalt3 tbsp. white balsamic vinegar4 tbsp. olive oilprepared spaghetti sauce, such as BertolliDaiya shredded mozzarellapine nutsItalian
