This is an inordinately impressive appetizer, considering the five minutes of work that go into it. And, best of all, it's mostly stuff that's laying around. Served with a baguette (or lime tortilla chips, when desperate), it is the perfect prelude to a cool summer salad or pasta dish. It is a riff off of a recipe I read long ago, I think in Gourmet.
2 1/2" slabs of feta
1-2 tbsp fresh chopped oregano (or 1 tsp dry, crumbled)
a few grinds of pepper
1/4 cup chopped roasted red peppers
2 tbsp olive oil
Place feta on ovenproof plate, sprinkle oregano and pepper over. Mix red peppers with oil, and drizzle over feta.
Place under broiler until golden brown, about five minutes.
Serve, with baguette or any other bready item laying around.
