Slow Cooker Lentil Tacos

I went to the beach with a group of 15 friends this weekend and I offered to cook dinner for everyone. The main conundrum was that I wanted a meal that could feed everyone (meat-eaters and vegetarians alike) and that wouldn't require me to sit inside and cook all day while everyone else was lounging in the sun. Enter: the slow-cooker. Tacos also allow for everyone to customize their meal. I made a ton of lentils for this (I had to use a 6-qt slow cooker), but half (or even quarter) the below recipe for a smaller yield. This recipe is based off of the great one over at Kitchen Belle.
