Add oil to a pan and add onion and jalapeño over medium high heat until softened. Add garlic and cook 1 minute more.
Carefully pour in the tomatoes...
...stir in spices and chicken broth. Reduce the heat and simmer for 10 minutes.
For a smoother sauce, transfer the contents of the saucepan to a blender or food processor...
...remove the feed tube (to prevent a build-up of steam and pressure), cover it with a dish towel...
...and process until smooth.
Serve with eggs, steak, chicken, and more!
