Spicy Slow Cooker Beef and Sweet Potato Stew

This is hands down the best beef stew recipe I've ever had. The Latin spices and the sweet potatoes in this beef stew sets this one apart. Traditional beef stew is kinda bland to me, but this one is pure greatness. Spicy, full of flavor with a bit of heat in the end. And the sweet potatoes are a nice change of taste and texture from traditional starchy potatoes. 
I substituted the poblano chilies in this recipe for some New Mexico chiles that I got from my friend Danielle last year. I still had one bag of them left in the freezer and tossed them in. Maybe that's where all the heat came from in this version. You just never know how hot or mild those New Mexico chilies will be. I don't mind, for me the hotter the better. But not so great for my kiddos. I'll file this recipe under, "Recipes my kids won't eat". Next time, I'll make it milder for them, substituting with roasted mild Anaheim chilies. Whether you like it spicy or mild this recipe is super delicious and easy because the slow cooker does all the work. Enjoy!
