Low-Carb Eggplant Pizzas

Preheat oven to 375 degrees F. Sprinkle eggplant slices with salt; place on a paper-towel-lined plate and let stand for 10 minutes. Pat with a paper towel to remove excess moisture. Brush both sides with oil and sprinkle with pepper; place in a single layer on a parchment-paper-lined rimmed baking sheet. Bake until tender and lightly browned, 18 to 20 minutes. Remove from oven. Increase oven temperature to broil with rack about 6 inches from heat.

Meanwhile, heat a medium nonstick skillet over medium-high. Add sausage and mushrooms and cook, stirring often, until the sausage is no longer pink and the mushrooms are tender and browned, about 6 minutes. Set aside.

Spread marinara evenly over the eggplant slices (1 1/2 to 2 teaspoons each). Divide the sausage mixture evenly among the slices and sprinkle evenly with cheese. Broil until the cheese is melted and browned, about 3 minutes. Sprinkle with basil and serve immediately.
