Baked Stuffed Onions with Spinach Feta

2 large sweet or Spanish onions (about 1-1/2 pounds total, peeled)
2 teaspoons olive oil
1 clove garlic
One (10-ounce) package frozen chopped spinach, thawed and squeezed dry
1 teaspoon fresh lemon juice
1/4 teaspoon freshly ground pepper
1/4 cup bread crumbs
1/4 cup (1 ounce) crumbled feta cheese

Preheat the oven to 350 degrees F.

Place the onions in a large saucepan and cover with water. Bring to a boil and cook until the onions are partially tender, about 10 to 15 minutes. Drain and cool; cut the onions in half crosswise. Scoop out the center of each onion half, leaving a 1/2-inch shell. Reserve the centers. If necessary, cut a small piece from the end of each onion shell so the shells will stand upright.

Prepare a shallow baking dish large enough to hold the onion halves in one layer with non-stick pan spray. Place the onions in the prepared dish, hollowed sides up.

Chop the reserved centers of the onions. Sauté in oil with the garlic in a medium saucepan until tender, about 5 minutes. Stir in the spinach, lemon juice, and pepper; cook until the liquid evaporates. Remove from the heat; stir in the bread crumbs and cheese

Fill the onion shells with the spinach mixture. Cover with foil and bake about 25 minutes. Serve hot.

Makes 4 servings (1 serving = 1/2 onion)
