Preheat oven to 400°.

Place the veggiest on baking sheet. I separated these on pieces of foil just in case one got done before the other. Drizzle with olive oil then toss with salt, pepper and the rosemary, (and crushed pepper if using). Spread the vegetables out on the sheet and place in oven. Roast for about 20 minutes until tende3r.

Remove the sheet pan from oven and mix the vegetables together. Immediately toss with butter and drizzle with the lemon juice and half the cheese. Season with more salt and pepper to taste.

Plate the beans and carrots and sprinkle with remaining cheese. Serve warm or room temperature.
