Add the ground turkey to the skillet. Break it apart with a wooden spoon and season with dried sage, ground cumin, salt, and pepper. Cook until the turkey is browned, about 7-10 minutes.
Pour in the chicken or vegetable broth, and let it simmer for about 5 minutes, allowing the flavors to meld together.
In a mixing bowl, combine the cooked sweet potatoes, milk, and butter. Mash until smooth and creamy, adjusting the consistency with more milk if needed. Season with salt and pepper to taste.
In serving bowls, spoon a generous portion of the creamy sweet potato mash, then top with the savory turkey mixture.
If desired, garnish with fresh sage leaves for an added touch of flavor and presentation. Enjoy your delicious Sage Sweet Potato and Turkey Mash Bowl!
