Blueberry Pie, No Bake

Ingredients

• 2 pints fresh blueberries, rinsed
• 2 tbsp. instant tapioca
• 2 tbsp. sugar, or to taste (you can use a sugar substitute since this isn't baked)
• Lemon rind, cinnamon (optional and to taste)
• Baked and cooled, or purchased pie shell (I use graham cracker crust)
