Add pasta to a saucepan of boiling water and cook according to instructions.
Heat a frying pan on a medium-high heat and add the pine nuts and pumpkin seeds and toast until brown.
Whilst the pine nuts and pumpkin seeds are toasting, place coriander, lemon juice, EVOO, salt & pepper to the food processor.
Once lightly browned/toasted, add the pine nuts and pumpkin seeds to the food processor. Blend until a nice consistency.
Drain pasta when cooked.
Stir pesto through and top with tomatoes.
Serve with a side salad.
