Heat 2 tablespoons of olive oil in a large, non-stick skillet over medium-high heat until shimmering.

Season 1 pound of evenly cut chicken breast pieces with 2 tablespoons of Cajun seasoning, salt, and pepper.

Add the seasoned chicken to the hot skillet and sauté for about 5-7 minutes until golden brown and cooked through.

In the same skillet, add another tablespoon of olive oil if needed, then add sliced bell peppers and 2 cloves of minced garlic. Sauté for 3-5 minutes.

Return the cooked chicken to the skillet with the sautéed bell peppers and stir together for an additional 2-3 minutes.

Taste and adjust seasoning if necessary before serving.
