In a medium saucepan, heat the olive oil over medium heat. Once the oil is hot, add the minced garlic and sauté for about 1-2 minutes until fragrant. Be careful not to let it burn!
Add the reduced sodium chicken or vegetable broth and canned tomato sauce to the saucepan. Stir to combine the ingredients thoroughly.
Incorporate the chipotle chilis in adobo sauce, Mexican hot chili powder, ground cumin, and kosher salt. Stir well to ensure that all the spices are evenly distributed.
Bring the sauce to a gentle boil, then reduce the heat to low. Allow it to simmer uncovered for about 15-20 minutes, stirring occasionally.
Taste your sauce and adjust the seasoning as needed. If you like it spicier, feel free to add more Mexican hot chili powder or chipotle chilis.
If you prefer a smoother sauce, transfer it to a blender and blend until you reach your desired consistency.
