01 - Combine oats, almonds, coconut, sunflower seeds, melted coconut oil, maple syrup, cinnamon, and salt in a bowl. Toss until evenly coated. Spread mixture in a dry skillet over medium heat and toast, stirring frequently, for 4-5 minutes until golden brown and fragrant. Remove from heat and set aside to cool completely.
02 - Place frozen strawberries, frozen banana, soaked and drained cashews, almond milk, maple syrup, vanilla extract, and sea salt in a high-speed blender. Blend on high until completely smooth and creamy, scraping down sides as needed. If mixture is too thick, add additional almond milk 1 tablespoon at a time until desired consistency is reached.
03 - Divide the smoothie mixture evenly between two serving bowls. Sprinkle the cooled granola crumble generously over the top. Arrange fresh strawberry slices, banana slices, chia seeds, and fresh mint leaves on top as desired. Serve immediately while smoothie is thick and granola remains crunchy.
