In a large skillet, heat 1 tablespoon of olive oil over medium heat. Add the kielbasa and cook until browned, about 5 minutes. Remove from the skillet and set aside.
In the same skillet, add another tablespoon of olive oil and sauté the onions until they are softened and slightly translucent, about 4 5 minutes.
Add the garlic and cook for an additional minute, until fragrant.
Stir in the mixed wild mushrooms and cook until they have released their moisture and are tender, approximately 7 8 minutes. Season with salt and pepper to taste.
In a separate baking dish, create a bed of the sautéed mushroom mixture, ensuring an even layer at the bottom. Sprinkle the chopped spinach on top of the mushrooms.
Place the browned kielbasa rounds on top of the spinach layer, followed by carefully cracking the eggs over the kielbasa. Season the eggs with salt and pepper.
Bake in the preheated oven for 12 15 minutes or until the egg whites have set and the yolks are still runny.
Remove from the oven and garnish with fresh parsley before serving.
