Combine the brown sugar, cinnamon, salt, cloves, nutmeg and orange juice into a bowl and stir. Combine that mixture with the mashed sweet potatoes and eggs and stir well.
Pour the sweet potato mixture into an aluminum pan that is sprayed with non stick spray. Sprinkle with the Great Grains Cereal and pecans, if choosing to do so.
Place the casserole over the grill and cook for 30-45 minutes or until golden brown.
Doneness: The key to doneness on this is to make sure that the eggs have completely cooked in the mixture which should take 30 minutes. This is hard to detect otherwise as it is mixed in with the mash and it's all liquified. Use 30 minutes minute as the gauge this time. Eggs: Sometimes sweet potato casseroles don't call for eggs but they are a great binder and hold the mash together nicely. You can leave them out and the mixture will be more soft. Meal Prep: This is 100% ready to meal prep. 1. Make the sweet potatoes early and then allow them to cool. Make the sweet potato casserole hours later and it should only take about 5 minutes to prep and get on the on the grill. 2. Make the entire sweet potato portion early and put in the refrigerator the NIGHT BEFORE MINUS THE TOPPING. If you put the topping on, it will get soggy and it will lose all the reason it's there to begin with. When ready to grill, remove from the refrigerator about 20-30 minutes before putting on the grill to allow to come to room temperature. Right before it's time to go on the grill, sprinkle on the topping and put on the hot 350-375 degree grill. Substitutions: Feel free to substitute 2 cans of sweet potatoes for the fresh version. Choose to leave out the orange juice and add milk instead. Change up the spices to your liking. Topping changes are endless. Add in Craisins to the Great Grains mix. Make a batch of candied almonds or pecans instead of the cereal. Keep the recipe the same and add marshmallows at the end and make a gooey topping. Pan Choices: We like to use disposable pans when making things like this that can stick or when we are entertaining during the holidays. It's just one less thing to worry about. This recipe can be done in a cast iron on the grill though. Liquid Casserole: You most likely overcooked the sweet potatoes. Make sure to check them often when you are cooking them to ensure they are just done and not too soft.Too Sweet: Since sweet potato casserole is suppose to be a savory dish, it's tough to make sure it is not too sweet and sticks to the savory side. If your version is a little too much on the sweet side, add a little bit of sour cream or buttermilk to cut it down. If you think it might be too sweet to begin with, cut out the brown sugar or only use ½ of it. It's much easier to ADD then take out. Make Two Versions: Divide up the sweet potato mixture and make ½ with the cereal mixture and ½ with the hold fashioned classic brown sugar/pecans or marshmallows.
