Here is my first shot at smoking cheese in my MES 30...AND the first time I used my AMNPS.
It was 32 degrees most of the day here in the Pittsburgh, PA area and windy. First, I boiled 2 doz eggs....didn't peel so well. I put in a chunk of Wisconsin cheddar, Longhorn, mild cheddar from a large supermarket, mozzarella from the same place, and from a discount food store I tried colby, mozzarella and pepper jack. I put in a large bag of string cheese and a chunk of chipotle cheddar that's been sitting in the fridge untouched for some time.
I filled 1 row of the AMNPS with the pellets that came with it (preseasoned the AMNPS per instructions).
I took the eggs out after 45 minutes and left the cheese in for about 3 hours. The internal temp of the MES kept inching up toward 90 after about 1.5 - 2 hours, so I would open the door about every 20 minutes to drop it back into the 70s. The eggs are tasty, the string cheese is fantastic. The rest of it is packed in the fridge for a while.
