Clean and drain the spinach well.
Peel and crush the garlic clove with the blade of a large knife.
Pour the olive oil into a large pan and add the garlic and sauté over medium heat for a couple of minutes.
Add the spinach, sprinkle them with a pinch or two of salt, and cover. Lower heat and cook until mushy - five to eight minutes.
Meanwhile, finely chop or trite the cheeses.
When the spinach is fully cooked, add the cheeses. Mix, over medium heat, until the cheeses have melted and have been well amalgamated to the veggies.
Serve hot.
