Halve, peel and thinly slice the onion. Peel and grate the garlic (or use a garlic press).
Peel and grate the ginger. TIP: Use a teaspoon to easily scrape away the peel.
Trim the green beans and cut into 3 pieces. Peel the sweet potato and chop into 1cm cubes.
Roughly chop the coriander (stalks and all).

Pour the cold water for the rice (see ingredients for amount) into a medium saucepan with a tight-fitting lid.
Stir in the rice and 1/4 tsp salt and bring to the boil. Once boiling, turn the heat down to medium and cover with the lid.
Leave to cook for 10 mins, then remove the pan from the heat (still covered) and leave to the side for another 10 mins or until ready to serve (the rice will continue to cook in its own steam).

Heat a drizzle of oil in a saucepan on medium heat.
Once hot, add the onion and cook, stirring occasionally, until softened, 4-5 mins.
Stir in the Sri Lankan style curry powder, garlic and ginger and cook for 1 min more.

Stir in the coconut milk, water for the sauce (see ingredients for amount), peanut butter, veg stock paste and sweet potato. Bring to a simmer, then cover with a lid (or foil).
Cook, stirring occasionally, until the sweet potato is just cooked, 10-15 mins. Add the green beans, cover again, then continue to cook until the beans are tender, 4-5 mins.

Meanwhile, zest and halve the lime.
Heat a small frying pan on medium heat (no oil).
Once hot, add the cashews and dry-fry, stirring regularly, until lightly toasted, 1-2 mins. TIP: Watch them like a hawk as they can burn easily.

Once the beans are tender, remove your curry from the heat and add a squeeze of lime juice.
Stir through three quarters of the coriander. Season to taste with salt and pepper if needed. Add a splash of water if it's a bit thick.
Fluff up the rice with a fork and stir in the lime zest, then share between your bowls. Top with your sweet potato curry.
Scatter over the cashews and remaining coriander to finish.
Enjoy!
