Red beans do contain higher levels of a toxic ingredient.  But soaking red kidney beans in advance and cooking at boiling for an extended period of time (more than 10 minutes) will diminish the toxicity.   In this recipe, we are preparing the recipe with canned or pre-cooked beans so it shouldn’t be an issue.  If you are cooking dried red kidney beans in advance to make this recipe, be sure you follow the instructions above to cook them (Soak and Boil for 10 minutes).
