In a small bowl whisk together all the sauce ingredients. Set aside.
Heat a large cast iron skillet over medium-high heat. While the pan heats up, wash and dry the peppers with a towel and add them to a large bowl along with the avocado oil. Toss to coat the peppers.
Once the pan is hot, add the oiled peppers to the skillet, turning them occasionally until they're nicely blistered and lightly charred, about 7-8 minutes. In the last 30 seconds, add a drizzle of tamari, soy sauce, or coconut aminos.
Remove the blistered shishitos from the heat and season with flaky salt. Serve with the dipping sauce and an extra bowl to discard the stems.
No shishito peppers? - though not the same, you can also use Spanish Padron peppers, which have a smokey, earthy, more complex flavor. Their taste is as mild as a green bell pepper, but 1 in 10 peppers is wildly hot.No limes? - you can also also use lemon juice.No honey? - use maple syrup.Add-ins - red pepper flakes or sriracha sauce for a bit of heat, or toasted sesame seeds for an extra crunch.
