Haven’t tried.
I don’t know who “Mom” is! Husband got this recipe at a Boy Scout Camp Out.

I prefer rinsing broccoli and adding it to the water, bringing water and broccoli to boil, then adding rice and let the broccoli cook along with the rice. If you do this you can just mix remainder of ingredients in and it is ready to serve…you will not have to bake for 40 minutes. You can, if you want, transfer to a glass casserole and microwave for about 5 minutes.

Pretty good.
Thinking you could add/substitute for peas & carrots: Asian Frozen Stir Fry Vegetables, snow peas, bean sprouts, baby corn, water chestnuts, sliced green onion instead of white onion….so many variations you could do.
