Cheese yogurt muffin

Since I made a batch of Greek yogurt recently, I surfed for a recipe which uses yogurt, shredded cheese (a packet expiring in oct) and lemon (I like lemon zest). I found one that requires the 1st 2 items, so I just added lemon zest and chocolate chips as a variation. I like the end product, but family isn't too keen on the hint of yogurt. Oh well, I'll finish most of the muffins myself with some help from S :)
