Tomatillos look like small green tomatoes with a husk on them, but they have a much firmer texture. This salsa depends on them for body and jalapenos for some heat. If you don't like it spicy you can use bell peppers instead of the jalapenos.
Place all the ingredients on a parchment paper lined sheet pan and roast at 400°F until the vegetables start to brown.
Blend until desired texture is achieved.
