Joy Larkcom puts fenugreek in with the leguminous category ... that would make peas and carrtos reasonable companions! Think I would add a row of spring onions or marigolds too just for good measure!
JL's book " Grow your own Vegetables" is one I would recommend to everybody. My 'bible' !!! ;D
Fenugreek will not fix nitrogen into the ground for the following crop if it's cold thus good for summer use ;D
