Heat a large skillet over medium heat. Add the olive oil, the veggie bacon, and sauté for one minute. Add the Brussels sprouts cut-side down in a single layer in the skillet. Add the orange zest and season with 2 teaspoons salt and 1 teaspoon black pepper. Pour the orange juice and let it simmer for 5 minutes or until the orange juice mostly evaporates and the sprouts are tender yet crisp. Taste and add more salt and pepper if you like. Toss gently to keep the Brussels sprout’s core intact. Remove from heat, add the pecans and serve warm.
