Ingredients

  • 3 tablespoons extra-virgin olive oil
  • 3 large bell peppers , thinly sliced
  • 2 medium red onions , thinly sliced
  • ¾ teaspoon salt , plus more to taste
  • 2 tablespoons dry white wine

    3 tablespoons extra-virgin olive oil, 3 large bell peppers, 2 medium red onions
  • Continue cooking for another 2–4 minutes, stirring occasionally, until the vegetables begin to soften and develop lightly browned spots.
  • Add the salt, rosemary, red pepper flakes, and dry white wine. Scrape the bottom of the skillet to loosen the browned bits. Continue cooking for 5–10 minutes, stirring occasionally, until the wine has evaporated and the peppers and onions reach your preferred texture.
    ¾ teaspoon salt, ½ teaspoon dried rosemary, ¼ teaspoon red pepper flakes, 2 tablespoons dry white wine
  • Taste and add additional salt if needed. Serve warm as a side dish or topping.

Notes

For Italian sausage: Cook the vegetables toward the softer end of the range and spoon them over cooked sausage links or sausage hoagies.
Wine-free: Replace the wine with a small splash of vegetable broth or water. Add lemon juice or a small drizzle of balsamic vinegar at the end if needed.
Mexican variation: Use red and green bell peppers. Omit the wine, rosemary, and red pepper flakes and season with dried oregano or fajita seasoning.
Balsamic variation: Replace the wine with 2 teaspoons of balsamic vinegar.
Gluten-free: The vegetable recipe is naturally gluten-free. Check packaged sausage, broth, sauces, seasonings, and rolls according to your needs.
Storage: Refrigerate in an airtight container for up to 3 days.
