Toss the sweet potato cubes with olive oil, salt, pepper, and paprika in a bowl until they are fully coated.
Spread the potatoes onto a large baking sheet and roast in a preheated oven until they are tender and the edges are golden brown.
Season the chicken with salt and pepper and sear it in a large skillet over medium-high heat until it is cooked through and has a golden crust.
Set the chicken aside to rest while you whisk together the chicken broth, maple syrup, mustard, soy sauce, and garlic in the same skillet.
Simmer the sauce over medium heat until it reduces and becomes glossy, then return the sliced chicken to the pan to coat it thoroughly.
Assemble the bowls by layering the cooked grain of your choice, fresh greens, and roasted sweet potatoes.
Top the bowls with the glazed chicken and drizzle the remaining sauce over the top before serving.
