Opposite problem man, im one of the least picky eaters. I understand your dilemma - my sister was a very picky eater growing up. We were not allowed to leave the table till our plates were cleaned. I would stall, then when my parents would turn their backs I would eat whatever she didn’t want to off her plate lol. Thank god I had a very fast metabolism. Even to this day I will eat any somewhat normal food, not crazy exotic shit or much anything raw except vegetables but it makes it a lot easier to bulk when your not really picky.
