To sweat out some of the moisture from the eggplant slices, place the sliced pieces of eggplant onto paper towels, sprinkle them with salt, and let them sit for 10-15 minutes.
Turn the eggplant slices over, sprinkle them with a little more salt, and let them sit for another 10 minutes.
In a large pan, heat up the coconut oil and then pan fry the eggplant at medium high temperature.
Let them rest on a rack or on paper towels.
Make tomato sauce with the recipe with already posted. (See Below)
In a little aluminum disposal container start building the eggplant parmigiana.
Start with a little tomato sauce on the bottom. Top it with a slice of eggplant and a pinch of dairy free mozzarella, and sauce again. Repeat this sequence until you get to the top of the container and finish with tomato sauce on the top.
You can also use an oven dish, like the one you would use to make a lasagna. Lay the eggplant parmigiana like a lasagna, once it is cooked you can slice it out in portions.
In a sauce pan over medium heat start sautéing the chopped onion (one medium) with 2 Tbsp of olive oil. Let the onions and olive oil cook gently until you get a translucent look. Next add the 2 cloves of chopped garlic and the can of whole tomatoes (do not drain the juice). Let the sauce pan simmer and gently cook for about 1 hour on medium low. Once your sauce has gently cooked for 1 hour, add 1 Tbsp of salt and ½ tsp of black pepper and blend in a food processor or with immersion blender. Be careful not to fill your food processor more than half way because the sauce will grow in volume.
