For a non GFCI breaker you could use one 20 amp dual breaker with 12/3 for a multi-wire branch circuit and then break it out at the kitchen into two 20 amp circuits. However, I don't know if there are any unique requirements for a dual pole GFCI breaker.

I think it it would be cheaper to use a standard dual pole breaker, and then put one GFCI receptacle for each circuit and wire it so it protects all receptacles downstream. I priced 20 amp GFCI breakers last week for my Square D panel and one 20 amp GFCI breaker costs a lot more than a couple of GFCI receptacles.

Codewise, i don't think i can do that.

Only 1 set of 2 GFCI plugs/Breaker Or 2 sets 2 split plugs/ 1 dual pole GFCI breaker.

Wondering i can can split 20 amp plugs.
