Dice that half red onion and toss it with apple cider vinegar and raw cane sugar. Set it aside so the flavors mingle and get pickly.
Chop your other half onion and carrot into little cubes. Cut the zucchini into small pieces too, so it cooks evenly.
Heat the coconut oil in the pressure cooker pot. Toss in mustard seeds and wait till you hear ’em pop and jump around.
Add onions, carrots, and the curry powder to the pot. Stir ’em around and let them sweat a few minutes till they smell fragrant.
Dump in the zucchini pieces and give ’em a quick toss with the spices and veggies.
Stir in mung dal and pour in the water and coconut milk. Season with salt. Lock the lid and set it to high pressure.
When the valve hiss kicks in, cook for about 8 minutes then use a slow release so the pot settles safely.
Open the lid and gently stir. Spoon the pickled onions over the dal and sprinkle fresh coriander. Serve with dollops of unsweetened soy yogurt and a squeeze of lime to brighten the whole dish.
Notes
Leftovers stay great for 4 days in the fridge. Sprinkle fresh coriander and lime right before serving for that fresh-out-of-the-pot flavor.
