Mild, quick-cooking sole makes an easy summer meal. Start with the best quality fish you can find. Don’t hesitate to ask your fishmonger what variety he or she is selling. Petrale filets are larger and more diamond-shaped than Dover sole, have a better texture and flavor and won’t turn mushy when cooked.
Serve the fish with some asparagus or green beans and cherry tomatoes, which need little work to heighten their flavors. Just toss them with olive oil and roast them to concentrate their sugars. If you have time, add a side dish of steamed new potatoes.
Both dishes can be prepared ahead, and you can serve them as a cold supper, if you’d like.
