This recipe is definitely spicy. Make sure that the poblano pepper is thoroughly cooked, not just charred on the outside, but soft on the inside. And pair the sofritas with things like refried beans or guacamole/avocado to help balance out the heat. If you don't like spicy food, also try using only half of a poblano, or cutting down on the chipotle peppers. Or, substitute the poblano with a roasted red bell pepper to get the same delicious roasted pepper flavor without the heat.
