Chop all veggies evenly in 2-inch strips
Press Instant Pot to saute mode and fry mustard seeds in the coconut oil (they will make a popping noise). Add curry leaves once mustard seeds are done popping.
Dump all veggies in the instant pot. Add in one cup of water, turmeric, and salt. Mix gently.
Put Instant Pot on Pressure Cook on high for 5 minutes. Quick-release pressure when finished.
Meanwhile, take one cup of thawed fresh ground coconut (you can buy frozen fresh chunks of coconut from Trader Joe's and put it in a blender to grind it up once thawed). Blend ground coconut with 1 cup of water, 5 thai green chilies, and 1.5 tsp of cumin seeds. Blend until it forms a thick coarse sauce.
Add this sauce to the cooked veggies. Add in 1 cup of yogurt. Add more salt to taste if necessary. Mix everything slowly but well (don't break veggies while mixing!).
Serve hot with rice or cauli rice!
