Stuffed Peppers Perfect for Entertaining

For whatever reason, stuffed peppers always look so impressive and fun… at least I think so. They’re perfect for easygoing entertaining. And, by using the slow cooker you dramatically reduce hands-on cooking time.

Hi. It mentions tempeh in the recipe but I don't actually see it on the ingredients. Personally I think this sounds great without it but thought I'd mention it since it's listed in the instructions. :)
