Place the egg in a small saucepan and submerge the egg with cool water. Bring the water to a boil uncovered. Turn off the heat, cover the pan and allow the egg to cook until soft boiled, 5 minutes. Transfer the cooked egg to ice water to cool completely before peeling.

Meanwhile, heat 1 tablespoon olive oil in a large skillet over medium heat. Add the garlic and cook until fragrant, 1 minute. Add the kale and use tongs to toss with the olive oil and garlic. Season with ¼ teaspoon salt, ¼ teaspoon black pepper and crushed red pepper and cook until slightly wilted but still crisp, about 2 minutes. Transfer the kale to a bowl.

In the same skillet, add the remaining olive oil and the sweet potatoes and season with the remaining salt and pepper. Cook, stirring occasionally, until fork tender, about 15-20 minutes. Remove and add on top of the kale.

Cut the soft boiled egg in half and serve on top of the sweet potatoes and kale. Add the avocado and enjoy immediately.
