Add thinly sliced onion and cook slowly to caramelize. Do not burn! Cook slow and easy.
While the onions cook down, add your diced eggplant to a baking sheet and sprinkle with salt, pepper, granulated garlic and drizzle with more olive oil and toss to coat.
Cook at 550 F for 10-15 minutes, tossing every couple of minutes to make even roasting.
When eggplant is roasted through, remove from oven and carefully add eggplant to the onions in the saucepan. Lightly combine and let cook for a minute or two.
Slowly and carefully, add the pizza sauce and cook to reduce slowly for 10-15 minutes. Set aside and let cool.
