I had a phobia of vegetables growing up. Still do now. Only ate sweetcorn until I was 16, now eat a small variety of veg but am terrified of tomatoes, onions, mushrooms, aubergines, etc. I'm 21 now.
Honestly, it's bloody difficult to feed myself and I feel sorry for people who I visit sometimes! (But they're usually fantastic with conferring with me before I turn up!) I tend to make soups often as I can handle the texture of soups with veg I'm not keen on then. I also have a list of veg that I want to try but haven't had the guts too yet.
You may think it's difficult for you to cater for people like me and the others on this thread, but really, it's worse to be like this! Because of my utterly pathetic phobia I'm severely anemic (I'm vegetarian too btw), very weak most of the time and genuinely cannot eat most veg. I miss out on so much good food because of the restrictions I've managed to put on myself and it's not a case of "Just eat it then". Though I did try that once, funny in hindsight! Took a great big bite into a tomato and nearly threw up over the counter.
I can eat: cauliflower, carrots, peas, beans, sweetcorn, parsnips, squash, potatoes obvs, asparagus and a few others. Though tbh, after the sweetcorn it was carrots and peas and I tried everything else within the past 18 months. I'm very proud of myself for adding so many new veggies to my diet in such a short time span!
I'm also a picker of food but will 'hide' veg in my own food to up my intake of vegetables. It's the texture that screws me over more than anything. I'm okay with root vegetables and squashes, which makes autumn a fantastic time of year for me!
