While the onions and bacon are cooking, place peeled sweet potato in microwave and cook for 2-3 minutes until it becomes softer. This will speed up cooking in the pan. Once the potato is done in the microwave, cube it and add to the soft onions and bacon. Continue to cook over low-medium heat for 5 more minutes, stirring regularly.
Add the kale to the mixture and salt and pepper and cook until the kale starts wilting.
Serve hash topped with a sunny-side up egg. Makes 2 servings.
