01 -  Place oats, milk, chia seeds (if using), maple syrup, ground cinnamon, and salt into a medium saucepan. Stir to incorporate, then set over medium heat and bring to a gentle boil, stirring occasionally. 
 02 -  Reduce the heat to low and continue cooking the mixture for 5 to 7 minutes, stirring frequently, until the oats are creamy and thickened. 
 03 -  Remove pan from heat. Mix in the protein powder and stir until completely dissolved and smooth. Add an additional splash of milk if a looser consistency is preferred. 
 04 -  While oatmeal simmers, combine the chopped nuts with melted coconut oil, coconut sugar, and ground cinnamon in a small bowl. Toss until the nuts are evenly coated. 
 05 -  Heat a small skillet over medium heat. Add the coated nuts and toast for 2 to 3 minutes, stirring regularly, until fragrant and golden. Remove from heat and set aside. 
 06 -  Divide the oatmeal between two serving bowls. Top each with the cinnamon crunch mixture and your choice of optional toppings, such as fresh fruit or Greek yogurt. Serve immediately while warm.
