I’m experimenting with a similar thing, but with Lentils. Kind of a Dahl. I’ve recently learned about a mirepoix and I’m trying to meld it into as many things as I can. I threw blitzed carrot, onion, garlic, celery, and broccoli stems, in pot until softened, added tomato paste, a red chilli meal base I had laying around, seared the spices a little then, tin tomatoes, Lentils, split peas, (yellow and green), cooked till it tasted cooked, I have no idea. Added a tin of coconut cream at end, cooked a few more minutes. Turned out great, needed lemon, but I didn’t add that because a kid hates it. I also added Greek yogurt. Bloody lovely, needed more spice, but I have the spice tolerance to kill a buffalo, so if I’m cooking for other people, I try not to do that.

I’m determined to keep a container with roughly chopped carrot, onion, celery, to blitz and add to stuff. It’s been super useful. Seared it and Added it to a pumpkin soup the week before.
