First, preheat the oven to 375℉. Then remove the stem and seeds from the poblano pepper and jalapeño. Add them to a sheet pan and roast them for 20-30 minutes. Keep an eye on them because they will cook fast being single peppers. Remove the corn from the freezer and allow to thaw.
Once they are roasted, you need to remove the skin and chop them up. You can leave the skin if you'd like, there will be a slightly more charred flavor.
In a large bowl, add in the thawed corn, chopped peppers, red onion, cilantro then juice the lemon and lime.
Lastly, add salt to taste then serve and enjoy.
