    1. Hi Roselyn, other peppers are higher in carbs then green ones. I would recommend using a nutrition calculator like MyFitnessPal to determine the nutrition information for other peppers.

    This is a great recipe. Took a bit of time to prepare vegetables and sauté them, but it was worth it. I’m not crazy about provolone cheese so I used a a Kraft cheddar combo cheese I had on hand. I used a higher fat content ground beef to safe money. It was really good. I heated up the left overs in my air fryer and it was amazing! I’ll make this recipe often.
