The disagreement started once we saw all those new Olive Garden commercials doing it. Her point is that nothing is going to taste great with the same thing used twice in a dish. I say differently. Like if you add a good Italian sauce or something and use rigatoni noddles.
A very common Indian daily meal is rotis (flatbreads) with thinly sliced, heavily sliced fried potatoes. Other meals include lentils (carb heavy) + rotis + rice. I’ve even had rotis + wheat & meat porridge. Carbmaxxing is a proud Indian tradition.
