Runny yolks are so trendy right now. Videos of golden liquid bursting out of its confines abound on social media. For the longest time I was squeamish around them, and preferred very well done eggs. I'm starting to come around, but I still don't love them. While I'm still adjusting, I'm perfectly content with this egg-free "carbonara" filled with squash, bacon, fresh mozzarella and sage.
