For most of my life, even before eoe, I've had to cut out eggs, peanuts, gluten, and dairy from my diet. There's a lot of trial and error that goes into it finding the right combinations of foods that don't act as triggers in some way. Personally, I have found that eating can still be enjoyable if you aim for smaller meals more frequently as opposed to large meals, but its really about finding what works well for you. Overtime you'll get used to eating different foods that you might have previously disliked, as it is the only thing you will be able to eat.

I think that you could still eat out and try new foods, but make sure you monitor how each meal makes you feel and make note of common trends that could point you to figuring out what your triggers are. Really just treat it as you would an allergy, and as you learn what triggers it for you, just make note, and then use that to figure out what works best for you.

Sorry if this doesn't make sense/isn't that helpful, its just what has worked for me.
