Cut the fennel into long strips, the onion into wedges. Put them in a baking tray, together with the chilli.
Mix the garlic with some balsamic vinegar and olive oil and brush the fennel and onion pieces. Pour over the soy sauce. Toss well.
Cover the dish with foil, then bake in a medium hot oven until soft. (Alternatively, you can pan-fry them.)
Meanwhile, mix the lentils and rice.
Add the fennel and onion, including the cooking jus. Cut the baked chilli into thin slices - add these to the salad. Season with salt and pepper.
Taste and adjust the oil, balsamic, soy and seasoning to your liking.
Mix in some chopped herbs and serve.
