Hey, I don't think you need to eat the raw vegies if you don't like them, life for Grok was adaption. Your hunting/ roaming grounds just happen to have cooked vegies and some vegies are better cooked, breaks down the fibres/ starches (? biology was a long time ago) . As long as you eat a variety of them you'll be fine.
Not strictly raw but washed broccolli for 30 seconds in the microwave allow to cool, stays firm with just a little softness.
