This Giada recipe is perfect! If you halve it, it makes plenty for 4 (when paired with veggies). The butter is optional, it still tastes delicious without (also of course good with olive oil and/or cheese).
Note: Half a recipe is 3/4 cup plus two tablespoon of dried corn grits. (1/2 cup plus half of 3/4 which is 3/8. 1/4 cup is 4 tbps, so 1/8 cup = 2 tablespoons. So 3/8 cup is 6 tablespoons, or 1/4 cup plus 2 tablespoons. So 1/2 c plus 1/4 c plus 2 tablespoons = 3/4 cup plus 2 tbsp).
