Preheat the oven to 425℉/218℃. I prefer to use a half sheet pan and no liner or parchment paper to get the best crispy texture for the veggies and gnocchi. I don't have issues with sticking since everything is tossed in olive oil, but if your sheet pan is prone to sticking, you may want to line it. If you don't have a half sheet pan, use 2 regular baking sheets so that the ingredients don't overlap. Rotate them halfway through cooking.
Put the gnocchi, broccoli florets, and red onion slices on the half sheet pan. Drizzle with olive oil. Use your hands or a spoon to stir until coated. Spread out in a single layer. Roast for 10 minutes.
After 10 minutes, remove the pan from the oven. Nestle slices of feta between the gnocchi and vegetables. Sprinkle the raw pistachios onto the pan. (If you only have roasted pistachios, just add those before serving instead.)
Return to the oven and roast for another 20 to 30 minutes until everything is browned to your liking. Stir halfway through cooking time to promote a more even browning if preferred.
In the meantime, whisk together the olive oil, lemon juice, honey, parsley, mint, salt, pepper, and red pepper flakes in a measuring cup or bowl.
When the veggies, gnocchi, and feta are finished baking, remove the pan from the oven. Whisk the dressing again to make sure it's well-combined before drizzling over the rest of the ingredients. Stir until coated.
Serve warm, garnished with more herbs and pistachios if desired. Enjoy!
