Rinse the French lentils and add them to a pot together with the bay leaves, salt and around 500g water. Cook the lentils for 22-25 minutes until tender. There should be enough water but feel free to add more if you feel like you need it.
Preheat the oven to 180°C fan. Once hot, toast the pumpkin and sunflower seeds for 8 minutes. Alternatively, toast the seeds in a fry pan on the stove.
Meanwhile, cut the capsicum and the cucumber into small pieces. Cut the cherry tomatoes in half and thinly chop the shallot. Add everything to the salad bowl.
Once the lentils are cooked, drain the water. Rinse the lentils with cold water until they're completely cooled. Add the cold lentils to the salad bowl.
Add the toasted pumpkin and sunflower as well as a handful of parsley leaves to the salad bowl.
To make the dressing, mix the wholegrain mustard, extra virgin olive oil and lemon juice in a small bowl. Season the dressing with salt and pepper to your liking.
Pour the dressing over the salad and mix everything together. Serve right away or store in closed containers in the fridge for up to 3 days.
