Preparation
Preheat broiler to high. Preheat a large skillet over medium-high heat with 2 turns of the pan EVOO, about 2 tablespoons.
Place a small sauce pot over medium-high heat with 2 turns of the pan EVOO, about 2 tablespoons. Once the oil ripples, add the onion and celery, season with some celery salt, hot sauce and a little pepper, and cook stirring frequently for 4-5 minutes or until the veggies are tender. Add the tomato sauce, bring up to a bubble then turn down the heat to medium-low and let it simmer while you cook the burgers.
