Season with salt, pepper, garlic powder, and nutritional yeast. Continue cooking until potatoes are golden brown and onions are a bit caramelized. Add pepper, stirring occasionally until tender.

For the guacamole, place the avocado in a small mixing bowl. Add lemon juice, salt, and garlic powder. Mash together with a fork; set aside.

For an over-easy egg, heat a medium-low non-stick frying pan until hot with non-stick cooking spray. Add eggs; cook until white is opaque, about 1 to 2 minutes. Carefully flip and cook for 1 minute.
