Bring a large pot of salted water to a boil; add potatoes, reduce heat to low and simmer until tender, about 8-10 minutes. Drain well; set aside.
Heat oil in very large nonstick skillet over medium-high heat; cook bacon until crisp, about 5-7 minutes. Drain bacon on paper towels; set aside.
Add potatoes and onion to same skillet; cook over medium-high heat, stirring occasionally, until beginning to brown, 5-8 minutes. Add garlic, salt and pepper, and handfuls of kale leaves, tossing with tongs as it cooks down. Cook, stirring occasionally, until kale is tender and starting to crisp, 3-5 minutes. Return bacon to pan and toss to combine.
When ready to serve, cook 4 sunny-side up eggs. Serve each portion of hash with an egg on top and hot sauce on the side.
Serving size: 1 1/2 cups hash and 1 egg
If you prefer, sauté the kale separately and when ready to serve, place kale on a serving plate, top with hash and then eggs.
