We eat quite a bit of salmon here and we often enjoy it plain - in this case Spring salmon fillets steam-broiled with a bit of lemon. I think @FrogPrincesse mentioned piperade recently and I made an attempt at something similar but substituting a bit of paprika and cayenne for the Espelette pepper. I added some summer squash to the onion, pepper and tomato mix and served it on top of some summer squash rounds. Tasty!
And simple but delicious Blackberry Pie Bars. (Served with a bit of ice cream.) So good!
