Cheesy Baked Spinach Artichoke Dip

Preheat the oven to 375°F (190°C).

In a skillet, heat olive oil over medium heat. Add diced onion and red bell pepper, sauté until softened, about 5 minutes.

Add chopped spinach to the skillet and cook until wilted, about 3 minutes.

In a large bowl, combine the sautéed vegetables, chopped artichoke hearts, shredded mozzarella, crumbled feta, salt, and black pepper.

Transfer the mixture to a baking dish and bake in the preheated oven until golden and bubbly, about 15 minutes.
