Heat the oil in a pot over medium. Add the garlic and sauté for 1 minute. Add the chopped spinach and cook until completely wilted.

Then transfer to a colander; drain, pressing to release all excess liquid.

Preheat oven to 400°F.

Meanwhile combine sour cream, salt, pepper and 2/3 cup of shredded cheddar and mozzarella cheese in a medium bowl. Add cooked spinach and asparagus; mix lightly.

Pour the mixture into a shallow baking dish and sprinkle with remaining cheese. Place on the middle rack of the oven and bake until cheese is melted and bubbly. Serve with French bread or cracker.
