Serious note
I don't know how the new tax laws may or may not impact this situation, but I would look into this issue. As stated it is taxable. You don't want to be hit with a higher tax bill than you thought when you went the R & B option.
Non-serious note
Hamburger/Chicken/Tuna Helper is another option. A little more, but at least you have protein and lunch/dinner/lunch/dinner with just 1 box.
