Hate lamb? Try lean ground beef, pork, chicken or turkey!
While homemade salsa verde is awesome (and my preference), commercial brands are fine. I like to use one that includes both tomatillos and green chiles if possible.
I live in a border town, and love the Mexican blend cheese at my local market (cotija, asadero, quesadilla, manchego, muenster, oaxaca). Use your favorite. I love a little crumbled cotija and its salty tang as a garnish, but that's completely optional.
