Preheat the oven to 350F/180C and grease the baking dish with oil. Dice the peppers and chop the broccoli into florets. To a large mixing bowl, add the eggs, salt, and black pepper. Whisk until thoroughly combined.
In a pan over medium heat, add 1 tbsp of olive oil. Add the broccoli florets, paprika, garlic powder, and onion powder. Sauté for 5 minutes while occasionally stirring until the broccoli is bright green and tender.
Add the cooked broccoli to the egg mixture. Add the chopped peppers and whisk to combine. Pour the mixture into the greased baking dish. Transfer the baking dish to the oven. Bake for 20 to 25 minutes until the eggs are fully set.
Meanwhile, slice the avocado, remove the seed, and cut it into cubes. Add the avocado to a small bowl together with the crumbled feta cheese. Add 1 tsp of olive oil, a pinch of salt, ¼ tsp red chili flakes, and ¼ tsp black pepper. Mix to combine.
Once the eggs are done, cut them into square slices. Serve each square piece on a plate topped with a scoop of the feta cheese mixture. Garnish with chopped parsley, and enjoy.
