I am pretty sure I would love this meal, I really like beans although I have never eaten oat beans, but I love oatmeal, so they must be very tasty, also cassava but I have never seen dried cassava flakes (this was a first for me) and all the other spices you used I love, so nothing could go wrong with this combination.
The story you tell reminds me of a saying in my country (Venezuela): "It is better to be on time than to be invited".
