Add 3 cups hot water into the oats. Hot water can come from the tap, you don't need to heat it up on the stove. Bring to a boil then turn to a low simmer for 25 minutes.
Add in milk, vanilla extract, salt, and blueberries. Stir then add in the lemon juice and zest. Let it simmer for another 15 - 20 minutes or until the oats become a porridge consistency. Remove from heat and let sit for 3-5 minutes.
Serve hot drizzled with 2 teaspoons of maple syrup per serving.
