Put the lentils in a large saucepan, cover with water and bring to the boil, skimming off any scum. Add the garlic, cumin and lemon slice, then reduce the heat and simmer for about 30 minutes or until the lentils are tender.
Meanwhile, to make the dressing, put the lemon juice, oil, coriander and pepper to taste into a large salad bowl, and whisk together.
Drain the lentils, discarding the lemon and garlic, and add them to the salad bowl. Toss gently to mix with the dressing.
Add the onion, apricots, peppers and broccoli florets, and mix gently. Crumble the cheese over the top, scatter over the sunflower seeds and serve immediately.

*Lentils are a good source of soluble fibre, which can help to reduce blood cholesterol levels. Lentils also offer protein and B vitamins. *The sunflower was first brought to Europe around 1510 as a decorative plant, but it wasn't until the 18th century that sunflowers began to be grown as a crop for the production of sunflower oil. Sunflower seeds are rich in healthy polyunsaturated fats and they are a good source of the antioxidant vitamin E, which helps to protect cell membranes from damage by free radicals and vitamin B1. They also provide useful amounts of the minerals zinc, iron, copper, phosphorus, selenium and magnesium.
