In France in the summertime, sardines are the most common thing you’ll find on barbecues, but here I'm cooking them in a slightly posher way. They’ve been butterflied and that way they’ll cook faster.
Eaten hot, warm or cold, it’s a great dish for a lazy summer day, grilled sardines with a confit of red onions.
Serve the tomatoes as an accompaniment. Really, it’s the simplest of dishes. And this will make a nice fresh accompaniment to the sardines.
