Step 1

Preheat the oven to 400°F.

Step 2

Slice the eggplant lengthwise, about 1/4-1/3 inches thick. Brush or rub a little olive oil on each side of the eggplant slices and place on a baking sheet lined with parchment paper or a baking stone. Sprinkle with salt and pepper. Place in oven for 7-10 minutes, or until eggplant is hot and starting to cook down.

Step 3

Meanwhile grab a skillet, add 1/2 Tablespoon olive oil and sauté the garlic and onion until soft (about 3-4 minutes). Season with salt and pepper. Add pizza sauce and spinach to the skillet and cook for 1-2 additional minutes until mixture is warm and spinach has wilted.

Step 4

Remove the eggplant slices from the oven, top each with the onion and spinach mixture. Sprinkle with cheese and chopped oregano. Place in the oven for approximately 5 minutes, or until the cheese has melted. Serve immediately with more fresh oregano and crushed red pepper.
