This is Albóndigas Soup, a.k.a Mexican Meatball Soup. The deeply flavored broth is spiked with chipotles and adobo sauce. You can certainly add as much or as little of this as you like. You can even omit the chipotle, but don't skip out on the adobo sauce. It adds a wonderful smoky kick. The meatballs are made from a mixture of beef and pork to which crushed tortilla chips and an egg are added as binders. I baked the meatballs instead of par-boiling them to achieve a nice crust. Simmer the broth and meatballs together with added carrots, zucchini, and rice. There is so much going on in each spoonful that you may not taste the same flavor combination twice in one bowl. You'll find the red broth pulling you back for more.
Don't forget about how to store your chipotle chiles and adobo sauce.
