We found 3 Reddit comments about SainSmart MAX6675 Module + K Type Thermocouple Thermocouple Sensor Temperature 0~1024℃ for Arduino. Here are the top ones, ranked by their Reddit score.
Simple SPI serial interface temperature output.High impedance differential inputs.Wide operating voltage range 3. 0 ~ 5. 5V, operating current 50mA.Module interface: GND VCC SCK CS SO.On-chip cold junction compensation.
Should be fine with a Type K. A thermocouple will also need a cold-junction compensation chip with amplifier. The MAX 6675 and 81255 are popular and I know I have a few Arduino boards with them downstairs somewhere, so they are available cheaply.

The way I did it would work with any OS that Artisan supports, as long as Python is installed. It uses the "external program" device to run a very simple python script that polls the arduino website thing.
As far as parts go, I used https://www.adafruit.com/products/2821, 2x http://www.amazon.com/SainSmart-MAX6675-Thermocouple-Temperature-Arduino/dp/B00PVTH4MW/ref=sr_1_16?ie=UTF8&qid=1463062785&sr=8-16&keywords=thermocouple and a bit of wire. I also got a battery for the huzzah thing so it doesn't add any power/network wiring to the roaster.
I could make more detailed write up if you're interested. It would take some tinkering, but would definitely be less expensive than most options.
Actually, I got the code from roastLogger. I'd give you links, but I'm not at the computer at the moment. Anyway, somewhere out there, roastLogger has an Arduino repository. Simply upload that to the Arduino...
As far as hardware, I just bought this thermocouple + amp board: https://www.amazon.com/gp/product/B00PVTH4MW/ and voilà.
