  • 3 bell peppers – you can use a mix of colorful peppers yellow, red, green, sliced
  • 2 onions sliced thin
  • 4 cloves garlic minced
  • 2 tablespoon olive oil
  • 2 teaspoon red chili flakes adjust as per spice tolerance levels
  • ¾ tablespoon red wine vinegar
  • Salt and pepper to taste
  • 2 ½ tablespoon mixed Italian herbs can use fresh herbs too


  • First slice bell peppers into thin strips. Try to slice uniformly sized strips.
  • In a non-stick pan heat olive oil. If using cast iron pan use little extra oil to keep them from burning.
  • Once oil is hot add thin sliced peppers, onions, dried Italian seasoning, salt and pepper to taste.
    Cook’s Tip: I like to dump everything at once and cook until together. Onions and peppers caramelize at the same time. It takes approximately 20 to 25 minutes to cook everything until vegetables are softened and caramelized.
    Alternatively you can first caramelize sliced onions for 8 to 9 minutes and then add in peppers and cook to caramelize. It will take about 12 to 14 minutes for peppers to caramelize and soften.
  • Begin to cook and on medium flame and saute it at regular intervals.
    Pro’s Tip: Do not over crowd the pan white you saute peppers. Leave room for space to help move around the sliced peppers white you saute them.
  • Do in multiple batches if you have to saute the peppers.
  • Once bell peppers begin to soften, add in minced garlic, red wine vinegar and continue to cook for couple of more minutes on low flame.
  • Once vegetables are tender enough, turn off flame.
  • Serve hot with fajitas, use it to stuff quesadillas, use it with toasted bread, with grilled chicken. You can use this dish with any meal of your choice.
