Preheat your oven to 400°F and line a baking sheet with parchment paper.
Toss the broccoli florets with half of the olive oil, salt, and pepper, then spread them on one side of the baking sheet.
In a small bowl, combine the almond flour, chopped fresh parsley, and a pinch of salt and pepper.
Place the cod fillet on the other side of the baking sheet, brush with a tiny bit of oil, and press the almond-herb mixture onto the top of the fish.
Roast the fish and broccoli for 12-15 minutes until the cod is opaque and the broccoli is tender and slightly charred.
While the fish roasts, warm the cannellini beans in a small saucepan with the remaining olive oil, minced garlic, and lemon juice.
Use a fork or immersion blender to mash the beans into a creamy consistency, adding a splash of water if needed to reach your desired texture.
Plate the white bean mash, top with the herb-crusted cod, and serve alongside the roasted broccoli.
