1Add 1 onion, 3 cloves garlic, 2 anaheim peppers to food processor and pulse to chop. Careful not to puree. Chop 4 tomatoes. Add all to bowl and set aside. Add Chipotle peppers in adobo sauce to food processor and puree.
2Ground beef with 1 tsp chipotle puree for mild sauce and 1 tsp salt. Drain fat. Add chopped tomatoes and reserved chopped vegetables to pan with ground beef. Add more chipotle puree to taste (careful this stuff is hot but it adds tons of flavor so don't omit altogether.) Simmer on med low heat until vegetables are soft and liquid is evaporated.
3while the ground beef simmers, chop remaining jalapeno, tomatoes, onions, lettuce for garnish. Grate cheese if it's not shredded. Put remaining chipotle puree in a small cup or jar so others who love heat can use as garnish for spice.
4I put everything on the table and have a build your own style burrito buffet, but if you are serving a lot or don't have the room you can wrap them yourself. I take 1 tortilla spread some re-fried beans all over, a dollop of the chipotle puree spread around, top with cheese (so it melts,) top with beef mixture, add fresh tomatoes, onion, jalapeno,add lots of lettuce and squeeze a heaping amount of sour cream all over. Roll up and Voila!
