Oh come one, I obviously don’t chop the lima beans or chickpeas. I don’t peel carrots, wash and then chop in under 20 seconds per carrot literally. If I want to make them really fine I use a peeler to thinly slice them into discs (I’ve gotten very good at this, can probably do a carrot in a minute. I don’t have a mandolin slicer).
Actually with a mandolin and skipping peeling you literally could do a carrot in 4 or 5 seconds, but the slices tend to be so thin you'd have trouble eating them as finger food. Anyway I'm keen to try your suggestion.
Also in the same vein if you want to try things out. Take eggplant/squash/beans/spinach etc., chop them up into cubes, slice some onions and some garlic, add a half teaspoon of black mustard, a pinch of whole cumin, some asafetida, salt, whole dried red chili peppers, about a table spoon of fresh grated coconut (you get frozen packs of pre grated coconut), and some tamarind or lemon juice in a pot. Cover, let it simmer or medium high for 10 mins and there’s another health snack to go. The whole thing takes me 15 mins to make and I can snack throughout the day.
