Bake bacon in preheated oven at 375F to crisp on slotted pan in middle of oven, 15-18 minutes. Allow to cool.
Meanwhile, trim tops and bottoms of tomatoes and slice into 4 slices each, no more than 1/2-inch thick. Salt the sliced tomatoes on each side and drain on a doubled paper towel for a few minutes then season with a little pepper. Dredge the tomatoes in flour, then coat in egg whites, then in breadcrumbs mixed with cornmeal, Parm and parsley. Heat 1/8 inch of oil in skillet over medium to medium-high heat and cook to golden and crisp, a few minutes on each side. Cool on cooling rack.
Combine meat with grated onion, hot sauce, Worcestershire, salt and pepper. Form 8
3-ounce slider-size patties, drizzle with a little oil. Heat large griddle or non-stick skillet and cook patties a couple of minutes on each side.
Combine sour cream with garlic, chives, lemon juice, salt, pepper and a dash or 2 of hot sauce, if you like.
Place burgers on bun bottoms. Top each slider burger with 2 slices of halved, cooked bacon, tender lettuce leaves, a fried slice of green tomato, sour cream and chive sauce and bun tops.
