Meals for vegetarians and with a fructan intolerance?

I recently got diagnosed with fructan intolerance via breath testing. The methane levels in my stomach skyrocketed after the fructan drink they gave me. This explains why I’ve been nauseous almost everyday for the past 10+ years. I had SIBO as a teenager and I believe that may have triggered the intolerance. I was retested recently and SIBO came back negative. I’ve been tested also for lactose and gluten intolerance and those were negative as well. I’m being tested for a few other sugar intolerances this month and I don’t feel the need to follow a restrictive 100% FODMAP diet if I already know what my trigger foods are.

I’m vegetarian and also have ARFID so eating meat or fish is not an option for me — even though I know it could improve my health, I gag and throw up from the anxiety and disgust. I do have dairy and I’m okay with eggs in my food, but eating eggs straight also makes me queasy for the same reasons.

I have this issue with a lot of foods but I desperately need to get on a healthy, low-fructan diet. Are there any other vegetarians here who have been able to successfully do this?
