Ingredients

1 cup rolled oats
1/2 cup orange juice (fresh squeezed from 3 Valencia oranges)
2 tablespoons vegan Greek Yogurt (plus a little extra for garnish/topping)
1 tablespoon fresh lemon juice from 1/2 small lemon
1/2 Honeycrisp apple, grated with the skin on (1/4 cup goes into the oats and a little more for topping)
1/4 cup raw or toasted walnuts, roughly chopped (plus more for topping/garnish)
1/4 cup fresh blueberries (for garnish/topping only)
1 tablespoon pure maple syrup
1/8 teaspoon ground cinnamon

Instructions

Step 1: The night before, add the rolled oats to a covered glass container along with the orange juice and a pinch of fine salt. Refrigerate overnight to allow the oats to absorb the liquid and soften.
Step 2: In the morning, stir in the vegan Greek yogurt, fresh lemon juice, grated apple, chopped walnuts, maple syrup, and ground cinnamon until well combined.
Step 3: Garnish with extra blueberries, chopped walnuts, grated apple, and a small dollop of Greek yogurt to add texture and flavor.

Tips & Variations

Toast the walnuts lightly before adding for a deeper flavor and crunch.
Substitute orange juice with almond or oat milk for a creamier texture.
Add a sprinkle of chia seeds or flaxseeds for extra fiber and omega-3s.
Use green apples instead of Honeycrisp for a tarter taste.

Storage

Store any leftover oats in a sealed container in the refrigerator for up to 2 days. Stir well before serving again. This dish can be enjoyed cold or warmed gently in the microwave for about 30 seconds.
