Preheat your oven to 400 degrees. Line a baking sheet with parchment paper, or foil, or both. Arrange the cod fillets on the baking sheet and add the broccolini, asparagus and tomatoes around the cod.
Drizzle olive oil over everything and then season the cod with the following: lemon pepper seasoning, smoked paprika, Herbes De Provence and then season everything with salt and pepper. Add some lemon slices and bake in the oven for 15 to 20 minutes (depending on how thick your cod fillets are). Do not over bake the cod! If you are unsure, bake for 12 to 15 minutes only.
Remove from the oven. Add the black olives, marinated artichoke hearts and garnish everything with the fresh parsley. Squeeze some lemon over everything and enjoy while hot!
