From mid-summer to early fall, depending on where you live, farmers' markets hold a bounty of fresh vegetables. They're scrumptious raw, in salads, and a myriad of main dishes. Especially when the cooler days of fall make you think of something hot for dinner, roasted peppers, zucchini, and other seasonal vegetables fit the bill. So simple, and so delicious.

This versatile roasted pepper and vegetable recipe makes a great side dish for almost any meal. You can use any number of seasonal vegetables, herbs, and spices. The secret is a hot oven, which helps caramelize the edges of the peppers, and gives the roasted vegetables a deep rich flavor.

  • 1 large red bell pepper, seeded and cut in eighths

Tips

  • If you want a simple, all-veggie meal, serve up a bigger portion of roasted vegetables with toasty garlic bread and a dry white wine like sauvignon blanc, pinot grigio, or a dry Orvieto.
  • Roasted vegetables make a rich contrast to light fish, like grilled flounder or sole.
  • Serve with a slice of lemon and crusty French bread.
  • A dry white also is the best complement with this meal.
  • If it's red meat you want, go all-in with grilled rib-eye or filet mignon. The rich flavors of the roasted vegetables and steak are superb partners.
  • Serve with wild rice pilaf or cheese-garlic rice and crusty bread.
  • A big, full-flavored red wine like cabernet sauvignon, malbec, or merlot makes the most of this menu.

Recipe Variation

  • Serving roasted vegetables as a side dish is not the only way you can use them. Make a roasted veggie omelet with cheddar or Monterey Jack cheese or add these hot morsels of goodness to your favorite polenta or risotto recipe for a one-dish meal on a chilly night. Serve with a big red wine and artisan bread.
