In a large container (at least 2 1/2 qt.) with a lid, combine oats, 4-grain cereal, dates, apples, walnuts, brown sugar, cinnamon, ginger, turmeric, and cloves.
For each serving, in a 1- to 2-quart pan, bring 1 cup water to a boil over high heat. (Or, in a microwave oven in a 2- to 3-cup bowl or glass measuring cup, heat 1 cup water on full power [100%] until boiling, about 2 minutes.) Stir in 3/4 cup spiced oatmeal mix. Remove from heat, cover, and let stand for 5 to 10 minutes, until it's as thick as you like.
