Creating the Chickpea, Spinach & Chorizo Frittata can be simple if you follow these steps:

1. Preheat Oven: Preheat your oven to 375°F (190°C).
2. Cook Chorizo: In a large oven-safe skillet, heat the olive oil over medium heat. Add the diced chorizo and cook until browned, about 5-7 minutes.
3. Add Vegetables: Add the onion and bell pepper to the skillet. Sauté for 3-4 minutes until softened. Then, stir in the chopped spinach and cook until wilted.
4. Prepare Egg Mixture: In a mixing bowl, whisk together the eggs, garlic powder, salt, and pepper until well combined.
5. Combine Ingredients: Add the drained chickpeas to the skillet, then pour the egg mixture over the vegetables and chorizo.
6. Cook on Stovetop: Cook on the stovetop for about 3-4 minutes until the edges start to set.
7. Bake: Transfer the skillet to the preheated oven and bake for 15-20 minutes until the frittata is set and lightly golden.
8. Add Cheese: If using cheese, sprinkle it on top during the last few minutes of baking, allowing it to melt.
9. Cool and Slice: Once baked, remove the frittata from the oven and let it cool for a few minutes. Cut into wedges and serve warm.

These steps will guide you in creating this incredible frittata effortlessly.
