Brats with Verde Sauce

This is a fairly simple sauce which is a bit different than the red salsas or sauces you usually see on brats or hot dogs. The brats were grilled on the Weber. For the sauce, start by rough chopping 1/4 of a large onion. We like to leave nice big chunks of onion in the sauce. When the onion has softened, add 3 cloves minced garlic, 1t ground cumin, 1/2t ground cardamom, 1/2t ground coriander, and as much heat as you like in the form of hot pepper powder. Bring the sauce to a slow simmer and cover until ready to serve. It is excellent used with a Dijon mustard.
