Prepare white rice according to package directions.
Meanwhile, heat oil in a large skillet set over medium heat; cook onion, celery and red pepper for 3 to 5 minutes or until slightly softened.
Stir in beans, tomatoes, broth, Cajun seasoning and cayenne pepper; cook for 10 to 15 minutes or until vegetables are tender and sauce is slightly thickened.
Stir in rice and kale; cook for 2 to 3 minutes or until kale is wilted and rice is heated through. Stir in lemon juice and parsley before serving.
For a kid-friendly dish, adjust the amount of Cajun seasoning.
Substitute vegetable-based chicken or sausage protein for black-eyed peas if desired.
