Preheat the oven to 350°F and grease a 12-cup muffin pan well.
Heat a skillet over medium heat with half the olive oil. Add the sausage and crumble it with a spatula. Cook until no longer pink, about 4 to 5 minutes. Transfer to a paper-towel-lined plate to drain, then wipe out the pan.
Add a little more oil to the pan, then add the onion and green pepper. Season with salt and pepper and cook 2 to 3 minutes, until soft and the onion is translucent. Let cool slightly, then combine with the sausage in a bowl.
In a separate bowl, whisk the eggs until fully broken down. Add the milk, garlic powder, and a sprinkle of salt and pepper, and whisk to combine.
Divide the sausage and veggie mixture between the muffin cups. Top with the diced roasted red pepper and cheddar. Pour the egg mixture almost to the top of each cup.
Bake for 25 to 30 minutes, until the eggs are set in the middle and the edges are lightly golden.
Let cool a few minutes, pop the egg bites out of the pan, and serve warm with hot sauce and fruit.
