Time to really upgrade your pallet. As a child you can easily say that you don't like veggies but it doesn't sit well when an adult says it. Experiment with a new veggie a week. Find a recipe with seasonings you like and go for it. If you end up not liking it, try something else. Give the veggies a chance. Your body WILL thank you for it.
There are lots of greens out there that make wonderful salads. No need to stick with one kind of lettuce.
i was like you several years ago. I couldn't say I didn't like veggies because I never branched out. I stuck with the ones I knew-- romaine, iceberg (which i no longer buy), carrots, celery, cauliflower, green peppers (no longer buy they are not ripe and the body does not digest easily), and kohlrabi (strange yes, but my grandmother grew them in her gardens). I also liked mostly raw. If I had to eat cooked I went with peas and green beans.
Then circle a few decades to present day. I met a doctor who introduced me to a raw food chef. I decided to try her out. i purchased her food baskets for a year. No meat, no dairy and no grains were in these baskets. The first time I got one, all i saw was veggies and nuts and seeds and two smoothies. I swallowed hard and tried the first bite of the all veggie lasagna and a spinach tartlet. And you know what--- They were really good.
So don't write off veggies or any other kind of food. the old Sam I am saying from Green Eggs and ham-- Try it, you may like it. So now other than mushrooms, i will eat my veggies in a box, I will eat them with a fox, I will eat them here or there, i will eat them anywhere. I do like my veggies. I do like them Sam i am.
