In a pan over medium heat, add the tablespoon of olive oil and sauté the asparagus for 5 minutes or until slightly brown. Season with salt and pepper and set aside.
In a different pan, very hot, melt the butter with blackberries until golden. Remove from the heat, allow to cool, and add lemon juice.
Put the bacon strips in a plate with paper towel and microwave in 1-minute intervals, until the bacon is brown and crumbles easily.
