Rice and Beans and Guacamole (No Added Fat)

My wife is still away, so I could cater to meals that I know my daughter would particularly enjoy. She loves brown rice, black beans, and guacamole, and that's what I made tonight.

I didn't get a chance to soak beans overnight, so covered them with maybe 1/4" extra water above the beans and pressure cooked for "0 minutes" - i.e., just let the Instant Pot come up to pressure then turn off. I put fresh water in, again to 1/4" above the beans, and pressure cooked for 25m (the beans ended up very soft - fine, but I could have cooked for 20-23m maybe).
