Put the cooked rice in a mixing bowl. Add the spring onions and parsley.
Add the olive oil and lemon juice and zest. Season with salt and freshly ground black pepper to taste, then toss gently to combine.
If you prefer, lightly grill the tomatoes until slightly softened and charred. Alternatively, simply halve them and add them to the salad.
Peel the avocado and cut it into slices. Drizzle with a little lemon juice to prevent it from browning.
Add the avocado slices to the rice salad and gently mix, allowing some of the avocado to break up slightly and coat the rice.
Peel the eggs and cut each into four wedges.
Divide the rice salad between two plates and arrange the egg wedges on top. Scatter over the pumpkin seeds and serve.
