Apple: you can shred them in a food processor, or by hand. If you don't have an apple, try fresh berries or a pear.Lemon juice: I skip this step if I add a bit of yogurt or whey because I prefer it a bit more on the sweet side, but up to you.Dried fruit: cherries, raisins, figs, and dates work well and add sweetness. If you're trying to limit carbs, leave these out.Seeds or nuts: Sunflower seeds, pepitas, chia seeds, pecans, almonds, or any mix works really. If you have nut allergies, stick with just seeds.Milk: I favor full-fat coconut milk for a creamier texture, but any milk works here. You may need a bit more milk depending on your other ingredients. Nuts don't soak up much milk, but chia seeds and quinoa flakes do.Yogurt: A bit of yogurt makes it creamier and tangier. I usually just add a bit of the whey (liquid that settles on top of the yogurt). When I do add yogurt I also add a drizzle of maple syrup or honey to balance out the tang.Cinnamon, Vanilla, and Salt: a pinch of salt elevates the flavor and can be added at any time. Optionally, you can add about a ½ teaspoon of ground cinnamon and vanilla extract, or a pinch of vanilla bean powder to bring up the sweetness further.You can store it in one big bowl in the refrigerator, or spread the mix across individual jars and place them in the refrigerator for quick meals over the next few days.If you replace some of the nuts and seeds with quinoa flakes it becomes a bit thicker and more like porridge.If it gets too thick after being refrigerated, add a bit of water or milk to it.I've also turned this into a nut and seed porridge by grinding the nuts and seeds until in crumbles before combing it with the apple and milk.
