Place sausages in a medium saucepan. Cover with water and simmer for 10 minutes or until just cooked through. Drain.

Boil the kettle. Place peas in a heat proof bowl and cover with boiling water. Stand for 60 seconds or until peas are defrosted. Drain and puree peas with the pesto using a stick blender. Or mash with a masher. Leaving them as smooth or chunky as you like. Taste and season with salt or some parmesan as needed.

Drizzle sausages with a little oil and brown in a frying pan or BBQ on a medium high heat.

To serve, divide pea puree between two plates. Top with sausages. Grate over some parmesan and pop lemon wedges on the side.
