Vegetarian friendly meals for a toddler?

My son is 17m. And he’s kind of a picky eater. I think it has more to do with texture. What are some healthy meal plans? I’ve tried looking up on google, but I’m having trouble finding stuff he could eat.

I also do not have an oven at the time, but I have an air fryer.

Also, is soy okay for him to eat? Like tofu? I’ve heard that’s not good for men to eat tofu because it can cause health issues.
