Prepare the ingredients by peeling and dicing the sweet potato into half-inch cubes and trimming the ends off the green beans.
Heat the olive oil in a large non-stick skillet over medium-high heat until it begins to shimmer.
Add the ground chicken to the skillet, breaking it into small crumbles with a wooden spoon, and season with sea salt, black pepper, garlic powder, and smoked paprika.
Sauté the chicken until it is fully browned and cooked through, which should take approximately 5 to 7 minutes.
Stir in the diced sweet potatoes and add the water to the skillet, then cover with a tight-fitting lid to steam the potatoes until they are fork-tender, about 6 to 8 minutes.
Remove the lid and add the green beans and rinsed black beans to the pan, stirring to combine all ingredients.
Continue to cook uncovered for another 4 to 5 minutes until the green beans are bright green and crisp-tender and the excess moisture has evaporated.
Remove from heat and serve the skillet meal immediately while hot.
