'Twas the week after a week of holiday parties, and all through the house, nobody felt like standing over the stove, not one single person, and especially not me. And yet, people needed to eat. The pantry presented all sorts of possibilities, and before I knew it, I'd thrown together lentils and pasta and olives and feta. What evolved was this Greek-inspired pasta dish with enough protein and heft to satisfy vegetarians and meat lovers alike. Lentil sauces for pasta are more common than you'd imagine, and tossing a handful of lentils into a traditional marinara boosts the nutritional value by adding plenty of fiber. I pulled the sauce off the heat before the lentils collapsed, because I love the more rustic texture, but you can let them cook a few minutes longer and watch them melt into the tomato sauce. Opa!
