Hi, "sod-ru-sod-hen" or "yak-roo" you can try this MAX6675, but can not order free sample from Maxim.

you can use PWM on MCU to control output driver for the heater, and ADC to monitor the temperature sensor

well , to control a heating system is not an easy thing, especially you want an accurate temp.
A closed-loop system is essential, and try some arithmetic like PID.
it usually take a long time to get a steady system:)

To interface microcontroller and a load (heater, for example) you can use an optocoupler and a triac .. see picture below ..
