Combine the sour cream, mayonnaise, blue cheese, parsley, lemon juice, salt, and pepper in a small bowl and stir until well blended and creamy. Add in a tablespoon or two of water to thin out the dressing. Use the back of a spoon to press some of the blue cheese crumbles into the dressing for even more flavor.
Preheat a grill or indoor grill pan to high. Add your bacon to a large skillet and cook until crispy. Set aside on a paper towel-lined plate to drain.
Brush the romaine with olive oil and place it cut-side down on the grill. Quickly sear until grill marks are visible and remove from grill.
Top each grilled romaine head with bacon, tomatoes, pecorino and blue cheese dressing. Enjoy!
Preheat the oven to 375°F. Add the potatoes to a large pot and cover with cold water. Add a large pinch of salt. Bring the water to a boil. Reduce to a simmer and cook the potatoes for about 8-12 minutes, or until just fork tender.
Meanwhile, lay the bacon onto a sheet pan in an even layer. Bake for about 25-30 minutes, or until crisp. Transfer the bacon to a plate lined with paper towels and allow to drain.
Increase the oven temperature to 450°F. Drain the potatoes and transfer them to a bowl of ice water for a couple of minutes. Once cool, transfer the potatoes to paper towels and let fully dry. Use your hands or a measuring cup to smash the potatoes flat. Transfer them to the sheet pan in the bacon fat. Drizzle olive oil over top to coat them well. Season with a generous pinch of salt. Roast the potatoes for about 20-25 minutes until crisp, flipping halfway through.
Meanwhile, whisk together the sour cream and lemon juice in a small mixing bowl. Stir in the lemon zest, chives, and scallions. Season with salt to taste. Crumble the bacon into small pieces.
Transfer the potatoes to paper towels to drain. Plate them with the sour cream sauce dolloped over top. Garnish with the bacon, freshly grated parmesan, and lots of freshly ground black pepper.
Add diced bacon to a medium skillet or sauce pan over medium heat. Cook until crisp. Remove bacon from pan and set aside. Add stone ground mustard, honey, garlic, and salt and pepper to the bacon drippings. Combine well with a whisk.
Add apple cider vinegar to the pan, whisking to combine as pouring. Continue to whisk until the vinaigrette has thickened slightly. Add bacon bits back to the vinaigrette, if desired.
Pour into a jar that has been warmed under hot running water prior to adding the hot vinaigrette to prevent the container from cracking. Best served warm or at room temp.
