Heat the olive oil in a large skillet over medium heat. Add the ground turkey and cook until it is no longer pink, breaking it up with a spoon as it browns.
Stir in the diced onion and cook for 3 minutes until it softens. Add the minced garlic and cook for 1 minute more.
Add the diced eggplant, Italian seasoning, salt, and black pepper. Cook for 5 minutes, stirring occasionally, until the eggplant starts to soften.
Pour in the marinara sauce and add the broken lasagna noodles. Stir everything together, then bring the mixture to a simmer. Cover the skillet and cook for 15 minutes, stirring once or twice, until the noodles are tender.
Remove the lid and drop spoonfuls of ricotta across the top. Sprinkle the shredded mozzarella over everything. Cover again and let it sit for 3 minutes until the cheeses melt.
Garnish with fresh basil leaves before serving.
