Preheat the oven to 350°F. Grab two large baking sheets.
Spread quick oats out onto the first baking sheet and the chopped walnuts onto the second baking sheet. Toast for 15 minutes, stirring every 3-4 minutes to ensure even browning.
During the last 5 minutes of toasting, add the shredded coconut to the pan of walnuts. Keep an eye on the coconut (it burns quickly!) and stir it twice while it toasts.
Let the oats, walnuts and coconut cool slightly, then pour the ingredients into a large glass bowl. Add the hemp hearts and chia seeds and set aside.
In a small saucepan, add the honey, brown sugar, coconut oil and salt. Heat the ingredients over medium heat until the sugar has dissolved, 3-5 minutes. Off the heat, stir in the vanilla.
Pour the sugar mixture over the dry ingredients and stir to combine.
Pour the granola into an 8"x8" pan that has been lined with parchment paper. Cover the granola with a square of wax paper, and using your hands, press the granola firmly into the pan.
Scatter the chocolate chips over the granola and, using the wax paper, press the chips into the granola with your hands.
Pop the granola into the refrigerator for 30 minutes to set. Once set, remove the granola, along with the parchment, from the pan and onto a cutting board. Cut the granola in half, then each half into 6 equal-sized bars. The granola bars are best eaten at room temperature, but I like to store them in the refrigerator (for up to two weeks) or the freezer (for up to two months) to stay fresh.
