Ninja Foodi Slow Cooker

For this 4 day breakfast meal prep recipe, I'm using my Ninja Foodi Cooker! I LOVE this cooker because, it's an electric pressure cooker, air fryer, slow cooker, oven, stove-top, steamer, and dehydrator all in one!
I use this cooking in appliance often like in my Oyster Mushroom Jackfruit Pot Roast, Stove Top Baked Beans, Instant Pot Potato Salad, and Air Fryer Buffalo Cauliflower.
And yes it slow cooks too! But if you don't have a Ninja Foodi, any slow cooker would work.

Notes
- Chia Seeds: One tablespoon of chia seeds will yield a thinner jam vs 2 tablespoons. Keep in mind that it thickens as it cools. Us the amount of chia seeds to your liking.
- Steel Cut Oats: Be sure to use traditional steel cut oats NOT the quick cook kind.
- Flaxseed & Wheat Germ: Flaxseeds can be substituted for my chia seeds in the oats if you desire. Wheat germ is not needed to make the recipe taste any better however, it adds significant nutritional value like extra fiber and vitamin E. I highly recommend not skipping this ingredient.
- Protein Powder: Be sure to use a good protein powder because the way your oats taste will take on that flavor. I didn’t add a sweetener to this recipe due to the protein powder having sweeteners in it. But if you feel your protein powder isn’t sweet enough, feel free to add 1 – 2 tablespoons of maple syrup, agave, etc to your oats as they cook.
- Three Methods of Cooking: Prep and cook time is based on the Instant Method because it is the fasted way to cook this recipe and great for meal prepping if you are prepping other recipes. However, I included other as to make this recipe to allow for accessibility and preferences. Slow Cooker Method can be great for overnight as it is hands off. The stove top method is traditional and can work if you don’t have any other equipment.
