The roasted pepper, onion & garlic that everyone is going sounds fab! How long do you roast it for? I've never roasted garlic before.
When i do couscous i use veggie stock cube, sping onion, chick peas, fresh herbs (parsley or corriander) dried mushrooms, red peppers & lemon juice. Tasty but the peppers, onion & garlic sounds super tasty!
