Start by preheating your oven to 400°F. As it's preheating, place a large baking sheet into the oven and allow it to heat up.
With a sharp knife, cut 6 heads of broccoli into bite-sized florets. Place them into a large bowl and season with 2 tbsp of olive oil, 1 tsp of kosher salt, and 1 tsp of freshly cracked pepper. Once your oven is heated, roast until golden brown. Remove from the oven and let cool.
Place a frying pan over medium heat. Add in 1 tbsp of olive oil; once heated, dump in ⅓ cup of panko breadcrumbs. Keep your eye on the pan as they can burn quickly. Keep stirring; fry for 3-4 min or until golden brown. Remove from heat and set aside.
Lastly, into a bowl, add 2 tbsp of mayo, 1 tbsp of lemon juice, 2 tsp of miso paste, 1 tsp of Dijon, ½ tsp of Worcestershire, 1 small minced garlic clove, 1 good crack of black pepper, and 3 tbsp of olive oil. Give that a good mix and set aside.
Add your roasted broccoli to a bowl, crumble in your bacon, pour over your dressing, and garnish with fried panko breadcrumbs and more Parm.
