Plain baked white fish with steamed greens. It's Monday low calorie dinner at its most honest — clean, simple, a fresh start to the week.
Preheat the oven to 400°F and lightly brush a baking sheet with olive oil.
Pat the white fish fillets dry and arrange them on the prepared baking sheet. Season evenly with salt and pepper.
Slice the lemon in half; squeeze half over the fish, reserving the other half for serving.
Bake the fish for 12–15 minutes, checking at 12 for flakiness and avoiding overcooking. The fillets should be opaque and just begin to flake.
While the fish bakes, steam the broccoli and spinach for 3–5 minutes, keeping the greens vibrant and tender without letting them get mushy.
Plate the fish and greens, drizzle with remaining lemon, and serve immediately while hot for optimal texture.
