Asparagus lovers on a budget will enjoy stretching a few spears of asparagus per person into a main dish. They'll love how the creamy center of the socca complements the tender richness of the roasted, then baked asparagus. People who don't adore asparagus can focus on the rich onion flavor and the addictive crispness of the socca itself.
This recipe is fast enough for a week night and luxurious enough to be a starter for a dinner party. It uses far less oil than an authentic socca, just enough to keep the vegetables from drying out and to let the socca crisp up.
