Onions turn brown and sweet when they're cooked slowly and allowed to caramelize. A bit of melted Brie cheese makes this savory appetizer creamy and wonderful!

Caramelized Onion and Brie Focaccia

2 1/4 cups biscuit baking mix
1 (1/4-ounce) package active dry yeast or 2 1/2 teaspoons active dry yeast
1 cup hot water
2 tablespoons butter, softened
1 large egg
1/4 cup butter
3 onions, peeled and thinly sliced
1 tablespoon red wine vinegar
8 ounces Brie cheese, thinly sliced

1. In a large bowl combine biscuit baking mix and yeast. Stir in hot water, softened butter and egg to form a soft dough.
2. Turn dough out onto a floured surface and knead briefly, about 5 minutes. Press onto a lightly greased baking sheet to 1-inch thickness. Cover and let rise for 30 minutes.
3. Meanwhile, in a large skillet melt butter and cook onions over low heat until soft, about 30 minutes. Add vinegar and cook 10 minutes more.
4. Preheat oven to 400°F (205°C).
5. Poke holes in the dough at 1-inch intervals. Spoon onion mixture on top. Arrange Brie cheese over onions.
6. Bake until golden brown and cheese is melted, 15 to 25 minutes. Cut into squares or wedges to serve.
