Completely separate rooms.
Put the food down for 10-15 minutes, pick it up at the end of the time. No envy over the other's food, no chance of food aggression, they don't get the choice of being picky.
I feed my dog in the kitchen and my foster in the bedroom. Takes just a few seconds to set the food down in one room and then the other room. If one finishes their food faster, they can chill until the other one is done. I pick up both bowls and then let both dogs loose.
