Add squash, beetroot and pumpkin trays to oven and bake for 55 minutes.
Meanwhile add pumpkin seeds and sunflower seeds to a baking tray and place in oven for 25 minutes.
While the vegetables and seeds are roasting, prepare the dressing. Add tahini, olive oil, lemon juice, honey, pinch of salt and garlic to a small jar. Shake vigorously to combine.
Once vegetables are roasted and can be easily pierced with a fork, remove from the oven.
To serve add lettuce leaves to a large salad bowl. Top with roasted vegetables, lentils, olives, seeds and dressing and toss to combine.
This recipe provides enough dressing to lightly dress the salad as there is a lot of flavour from other elements of the salad. For a more liberal dressing, double the ingredients for the dressing. Excess dressing can be kept in a sealed jar in the fridge for 4-5 days. If making this salad for meals throughout the week, refrain from dressing until the day of eating.
