Spinach Artichoke Dip

Luke has been asking me to make him something in a bread bowl for months now, so I took advantage of having visitors over so we wouldn't have to eat the whole thing ourselves. Please note that despite Aziz, Jo and Jan helping us out, we continued eating this for several days. Next time I will definitely half the recipe.

2 pounds fresh spinach washed ( or 2 packages of Frozen)
1 large can of artichokes, chopped

2 sweet onions diced
2 tablespoons butter
1 pint plain yogurt
1 teaspoon salt
2 teaspoons freshly ground black pepper
1/2 cup walnuts lightly toasted

Directions

In a large pan cook spinach in water that clings to the leaves until it wilts.
Drain and rinse under cold water and gently squeeze out excess liquid.
Chop finely and reserve.
In medium pan cook onions in butter over medium heat until well caramelized.
Cool then mix with spinach, artichokes, yogurt, salt and pepper.
Sprinkle with toasted walnuts and serve in a bread bowl
