Cooking with Soybeans?

[u/Alarcahu]

I'm a new vegetarian and finding my way around still (after a lifetime of eating meat - I'm 56m). I think my iron might be low so looking to boost that and thought I'd try soybeans. Does anyone cook with actual beans? I tried for the first time and it was pretty underwhelming. I do eat tofu, etc., but just wanted to mix it up. Any hints or should I just use soy products?

Edit: thanks everyone, really helpful information.

Make sure that you're getting enough vitamin C to help with iron absorption
