In a large skillet over medium heat, cook the bacon until crisp. Remove and place on paper towels to drain. Remove all but 1 teaspoon if you have more grease. Add the olive oil to the pan, once hot add the grape tomatoes and cook, stirring occasionally for 2-3 minutes. Add the spinach and cook, stirring frequently, until just starting to wilt. Season with sea salt and freshly cracked pepper, to taste. Serve immediately. Enjoy.
