Spray a sheet pan with cooking spray. Add cubed sweet potato, potato, red onion, red pepper and zucchini. Drizzle on the olive oil, sprinkle with salt and pepper and toss well. Roast for 25 minutes, tossing once during cook time. You want the potatoes to be golden and softening.
Once potatoes are cooked, sprinkle with garlic and toss into the potato and vegetable mixture. If you are using meat, add the cooked bacon or sausage to the mixture.
Add eggs and feta on top of the potatoes. I like to scoop the mixture together a bit, so the eggs sit on top and can cook into the potatoes and vegetables.
Stick the pan back in the oven and bake for 8-12 minutes depending on how cooked you like your egg yolks. I definitely like them a little runny!
