Prepare the Rooibos Iced Tea: Bring 4 cups of water to a simmer, then remove from heat.
Steep rooibos tea bags for 10 minutes.
Remove the tea bags, sweeten with honey or sugar to taste, and refrigerate until cool.
Serve over ice.
Prepare the Hot Dogs: Preheat a grill or grill pan over medium heat.
Grill the hot dogs, turning occasionally, until nicely charred on all sides (about 5-7 minutes). Ensure the internal temperature of the hot dogs reaches at least 160°F (71°C) for food safety.
Assemble the Hot Dogs: Open the buns and place tomato slices along one side.
Place a hot dog in the middle and a pickle spear on the other side.
Spread relish along the top. Evenly distribute pepperoncini and minced onion.
Sprinkle with celery salt and top with mustard.
Arrange hot dogs on a serving plate. Serve with carrot sticks and ranch dressing on the side. Enjoy with a glass of chilled rooibos iced tea!
