Preheat oven to 400 degrees. Line a large baking sheet with foil for easy clean up.
In a bowl combine broccoli florets, pine nuts, and bacon pieces, adding in garlic salt evenly. Pour over with olive oil and combine with hands to make sure all the broccoli gets some olive oil.
Pour broccoli mixture onto baking sheet and spread out evenly as the bacon will have a tendency to stick together.
Bake for 40 minutes until broccoli looks roasted and bacon is cooked crispy, removing broccoli from oven to stir and flip every 10 minutes (or else you will burn the dish).
Season with optional pepper and a dash of freshly grated parmesan.
