you’re absolutely right, it could be modified to be made much more low cal and would still taste good.
I was diagnosed with adult diabetes a little over a year ago.
First thing I did was remove all the “white’ food from my house (White bread, pasta, rice, sugar, cakes, cookies, etc)
I replaced it all with whole grain products, and they actually taste better. More filling too, so I eat less of it.
It’s a good way to lower carbs...offset them with FIBER!
And still eat like a KING!
