Notes
Adapted from MyRecipes.com
Use rotisserie chicken to speed things up or alternatively use up leftover chicken you have in your fridge.
If you have raw chicken make sure to cook it first.
Feel free to use low-fat cheddar to reduce calories.
Make sure to use quick-cook grits for this recipe.
Leftovers can be stored in the fridge for 2-3 days and reheated until piping hot. As grits absorb liquid you will probably need to add a little extra liquid when reheating (stock, water or milk).
