In a small saucepan, bring the water and a pinch of sea salt to a boil.
Whisk in the grits, reduce the heat to low, cover, and simmer for 15-20 minutes until the liquid is absorbed and grits are tender.
While the grits cook, heat the olive oil in a medium skillet over medium-high heat.
Add the ground turkey to the skillet along with the garlic powder, smoked paprika, remaining salt, and black pepper.
Sauté the turkey, breaking it into small crumbles with a spatula, until it is browned and fully cooked through.
Add the baby spinach to the turkey and stir for 1 minute until just wilted, then remove the skillet from the heat.
Once the grits are finished, slowly whisk in the liquid egg whites and nutritional yeast, stirring constantly over low heat for 2-3 minutes until the grits become thick and creamy.
Transfer the creamy grits to a bowl and top with the savory turkey sausage and spinach mixture.
