Rinse and slice green beans thinly and set aside.
Mix shredded coconut with yellow curry powder, fish sauce, salt, and pepper.
Add sliced curry leaves, green chili, and ginger to the coconut mixture.
Heat a skillet on high and add coconut oil. Add mustard seeds and let it splatter. Add shallots and sliced garlic and sauté for few seconds. Add the coconut mixture.
Fry for couple of minutes until coconut warms up and becomes toasted a little.
Add green beans and quickly mix with toasty coconuts and cook for another couple of minutes or until green beans start to soften up. You could cook the beans longer if you like the green beans very soft. but I like mine to have a little crunch.
Turn the heat off and adjust the seasoning. Finish with lime juice.
Serve warm on the side with rice and curry or on its own.
