A little help here...please

So I am trying to plan a little bit in advance for my next ww journey and I know my biggest issue is that I dont like veggies. I am hoping that someone can give me tips or links on how to cook veggies so that they taste better in a healthy way. I am will to try veggies again but I guess I just don't know what to do with them. 

What I KNOW I  like

sweet potato

white potato

cucumber

lettuce

cooked carrots in soup

peppers

I really do not like, not even a little....

celery

onions (except powder to season)

broccoli (except in broc and cheddar soup)

butternut squash

I have had yellow squash cut up really tiny, mixed in risotto and I was ok with that so it is one veggie that I am really interested in finding a good recipe on. 

Any tips would be lovely!! Thanks in advance!
