In a mason jar, combine the red wine vinegar, mustard, oil, garlic, Italian seasoning, and a pinch of salt and pepper. Screw the lid on tight and give it a vigorous shake until well blended. Give it a taste and adjust seasoning accordingly, adding more salt or pepper as needed. Set aside. Dressing can be made up to three days in advance and kept in the fridge until ready to use.

To make the salad, place the lettuce in a very large bowl. Add in the tomatoes, eggs, bacon, chicken, avocado, and feta. Drizzle in about half of the dressing and season with a pinch of salt and pepper. Give it a toss until evenly combined, adding more dressing as you'd like.

Cut the rolls into little bread bowl, by slicing a bit of the top off and then scooping out some of the insides. Fill each with the salad and garnish with chives. Serve immediately. Enjoy!
