Cook the rice as per packet instruction. Transfer it to a bowl and allow it to cool.
To cook the trout: Heat the grill to high. Brush a little of the melted butter over a baking tray. Lay the trout fillets on top, skin side down, and brush over the rest of the butter. Season with a little salt and black pepper. Cook for 4-6 minutes depending on the size of the trout fillets.
The dressing: Mix the dressing ingredients together in a small bowl. Taste and season. Combine the scallions, carrot and mangetout together in another bowl and stir through a tablespoon of the dressing. Add the rest of the dressing to the rice and stir well.
To poach the eggs: Bring a large pan of water to the boil. Add the vinegar and season with a little salt. Reduce to a very gentle simmer. Break two of the eggs into the water and simmer for 3-4 minutes until just cooked but still soft on the inside. Remove with a slotted spoon and drain well on kitchen paper. Repeat with the remaining eggs.

To assemble the bowls: Divide the rice between four bowls. Flake the warm trout then arrange it along with the carrot, mange tout and avocado on top of the rice. Then add a poached egg into each bowl and sprinkle over the sesame seeds. Season the egg with a little salt and black pepper. Serve immediately
