Spring is in the air and what better way to celebrate the season than with delicious and colorful roasted spring vegetables? Serve them over creamy polenta for a healthy vegetarian dinner that's perfect for the changing seasons.
Toss the asparagus, radishes, zucchini, snow peas, and onion with olive oil and season generously with salt and pepper. Spread onto a sheet pan in a single layer and roast until tender and beginning to char, about 30 minutes.
Meanwhile, combine the vegetable broth and water in a medium saucepan. Bring to a boil over medium-high heat, then reduce the heat to low. Slowly whisk in the polenta and cook for 1 minute, until smooth and creamy.
Stir in the mozzarella and butter. If the polenta is too thick, stir in a little more broth or water to loosen. Season to taste with salt and pepper.
Spoon the polenta in a serving dish; top with roast vegetables and fresh basil.
