Forget filet mignon. These 3 cheap meat cuts taste better in a slow cooker. Do you know what they are?

It's common knowledge that slow cookers are great for turning cheaper, lean cuts of beef into melt-in-your-mouth pieces of heaven. That's because, while fat melts away in the early stages of cooking, it's the collagen found in these economical cuts that break down in the later stages of cooking. When you have hours and hours of cook time, this inevitably turns otherwise chewy pieces of beef into delectably tender morsels. In fact, these economical cuts actually turn out better in a slow cooker than their more expensive, fatty counterparts, which would simply dry out if cooked for too long.

But which cuts should you keep an eye out for when you visit the butcher? Here's a short list of some of our favorite lean cuts of beef, and our favorite recipes that use them.
