Heat sesame oil in a large skillet over medium heat. Add tofu and cook for 3 min. (or longer if you like your tofu firmer- I cooked mine for approx. 8 min). Add tamari, zucchini, Swiss chard, scallions, cayenne and pepper. Cook until vegetables are tender (approx. 5 min.).
While vegetables are cooking, warm the tortillas in the microwave . Place one tortilla on a microwave safe plate and cover with a moist paper towel, layer another tortillas and then another moist paper towel. Continue until you have four tortillas (paper towel on top) and heat for 30 seconds. Repeat with the other 4 tortillas.
When vegetables are tender, mix in kimchi and remove skillet from heat. Divide and spoon tofu mixture into 8 tortillas. Squeeze the juice of lime , and garnish with chopped chives, chopped cilantro leaves and raw unsalted peanuts.
