There ARE no tasty recipes for couscous - it's the world's most boring food!
Actually we have it every so often at my insistence, cue moans from dh.
You can use it as a change from rice. Just pour boiling water over & leave 5 mins - more boiling water as needed. A stock cube makes it less dull, but a bit salty for kids. OK with chilli.
Stir oven-roasted veg thro' & serve cold for salad (peppers, onions, courgettes, aubergines, tomatoes - dice, then chuck into pre-heated tin containing olive oil, shake about a bit, drizzle with balsamic vinegar - 30 mins @ 200C).
Or use for stuffed peppers - cook with boiling water, then spoon into halved, deseeded peppers. Top each with spoonful of pesto, chunk feta cheese, halved olives &/or cherry tomatoes. 40 mins in oven at 200C.
