Saute one medium(ish) diced onion in a pan with approximately 1/4 C olive or grape seed oil.

Add 2 cloves of crushed garlic and 1/8 C. flour and cook for a minute or two.

Add 6 C of water OR chicken broth. Typically I use water then adjust the flavor with 1 or 2 T. of chicken base at the end of cooking. This allows me to adjust the flavor and salt at the end of cooking. Cook until thickened over medium heat. Add 2 T. cumin and the juice of one lime (I used RealLime because I didn't have a fresh lime but it is actually better with a real lime) and a 14 oz container of canned Rotel-style tomatoes. I added some TrueLime with Cilantro to make it extra lime-y. I typically drain and rinse the tomatoes so the soup isn't pink but it's completely up to you if you like your soup pink. Add diced or sliced chicken and cook until the chicken is cooked through. If you already have some cooked chicken you can also slice and use it, or use 2 small or 1 large chicken breast. How you put the chicken in is completely up to you. You can also add a diced jalapeno at this point if you like your soup spicy.

Cook until the chicken is cooked through and add some fresh cilantro.

Cook for just a minute to heat the cilantro through and adjust the seasoning with chicken base if you did not use stock (or salt if you need it).
