There is that, a practice I can appreciate, still, on the stove is so quick and easy, it doesn’t have to be watched long.
I have been buying frozen rice and vegetables in microwave bags. They are super handy, and taste great. I don’t know if they have a brown rice option or not. What I get is a dollar a bag, and contains enough to be pretty filling. I like to toss in some chicken chunks, or meatballs, etc.
Anyway, those are quick, and foolproof, and would be great for work lunches.
