I am cooking my lunch. It's red lentils, onion, potatoes, chilli, tomato paste, and lots of water. The cooking is slow. Around an hour. And when it is nearly done I'll add dome peas and corn and capsicum to add texture and flavour and maybe some extra nutrients.
Soaking your legumes (your lentils) first (preferably overnight but even for a few hours) before cooking reduces both phytic acid (an anti-nutrient that binds up minerals making them unavailable for absorption) and cooking time. You get more nutrition with less cooking time. It's a win win.
Chips rarely feel like enough.
That's because in the West they are a side item, not the main course.
Speaking of eating against culture, this man ate only spuds for an entire year and wound up in better health than when he started.

That's lots of spuds I imagine though. Heh.
