In a large pot, bring salted water to a boil. Add the baby potatoes and cook for about 10 minutes or until fork-tender. Add the green beans to the pot and cook for an additional 3-4 minutes until bright green and tender-crisp. Drain and set aside.
In a large skillet over medium heat, cook the chopped bacon until crispy, about 5-7 minutes. Remove the bacon with a slotted spoon and drain on paper towels, leaving the bacon drippings in the skillet.
Add the olive oil to the skillet with the bacon drippings. Once hot, add the cooked potatoes and green beans. Sprinkle the ranch seasoning mix over the vegetables and toss to coat evenly. Season with salt and pepper to taste.
Cook for an additional 5 minutes, stirring occasionally, until everything is heated through and slightly crispy.
Remove from heat and stir in the crispy bacon. Garnish with fresh parsley before serving.
