actually describing food, or things that could be food.
*rap* + *saint*
TAPIR (TAP = rap [on a door], PIR = Sufi master) - like tapir meat. Thanks @Stiv for the second half.
double + heir
BISON (BIS = twos, SON as heir) - like bison meat.
percent + fool
BACON (BAC = blood alcohol concentration or percentage of alcohol in the blood, CON = fool [as a verb])
wheel + honey
CAMEL (CAM = wheel, MEL = honey) - like camel meat.
