Heat the oven to 400°F. Place an egg in a pot and cover with cold water by 1-inch and bring to a boil over medium heat. Remove the pot from the heat and let it cool down for about 8-10 minutes. Drain and cool the hardboiled egg under cold water and peel. Heat 1tsp of olive oil on a nonstick pan, add spinach and cook until wilted, 3 to 4 minutes. Heat up the tortilla. After it is heated spread the mashed avocado evenly on the tortilla. Divide the spinach and tomatoes evenly among the tortilla, leaving an empty space in the center for an egg. Add a pinch of salt and pepper and enjoy.
