Baked cod and capers, with fennel and potatoes

Trying to get fish into primary victim is a losing battle.  This was eaten - but with a face like a slapped kipper.  I thought it was refreshing, light and tasty.  So, roast par-boiled potatoes in olive oil, with wedges of fennel - for about 50 minutes.  Bake cod on lemon slices, drizzle of olive oil, tablespoon each of capers and black olives - cracked black pepper - with a good squeeze of lemon juice.  Cod takes about 20 minutes - cooked frozen peas.  Easy peasy then lemon squeezy.  As I said victim ate and grimaced, me and second victim enjoyed it.  Primary victim grinned when I declared we couldn't have it again for at least 3 weeks.
