Preheat oven to 450 degrees.
Place sweetpotato slices on a parchment lined baking sheet and lightly coat each side with olive oil and sprinkle with salt and pepper.
Bake for 20 minutes, flipping toasts halfway through for even baking.
Cool slightly and top with cream cheese, avocado, and radish.
Using a sauté pan, add a little butter to the pan and allow to get hot. Add the gg and allow to cook for about 30 seconds. Reduce heat and cover pan for 3.5 to 4 minutes. Uncover.
Top the toasts with the fried egg and serve. Garnish with additional chopped chives.
