Interested in trying firm tofu. What’s something that’s easy/quick to make with firm tofu?

I’ve never had tofu before, always been curious about it but also a little intimidated, and I’ve noticed lately I’m leaning towards an all veggie diet (meat is too damn expensive istg). This seems like a good time to expand my taste horizons.

I know there’s different firmness to tofu and that it more or less soaks up the taste of whatever it’s put with, but that’s about it.

Got any suggestions for easy and/or quick tofu recipes? Preferably cold dishes, bc it’s so hot I don’t feel much like standing over the stove these days, but I’m not strictly opposed to a good grilled/fried tofu recipe suggestion.

For example, I make a chickpea salad to take as my lunch almost every week and was considering tossing some chunks of tofu in it. Would that even work, given how little dressing I put on my chickpea salad?
