In a hot frying pan, add the avocado oil, onions, and jalapeño. Sauté, stirring often until onions are soft. Then add the minced garlic and ginger and cook, stirring for a minute until fragrant.
Add seasonings, broth, tomatoes, tomato paste coconut milk, and maple syrup. Stir and cook over medium heat for a few minutes.
In a separate bowl, add 1/4 cup of the sauce with 1-2 tablespoons of cornstarch. Mix until there are no lumps. Then pour the cornstarch mixture into the pan. Stir and heat until it gently bubbles and thickens. At this point, you could take a handheld immersion blender and blend if you wanted to make the sauce smoother for little kids, optional.
Add the chicken to the pan.
If desired, add 1/4 of heavy cream or sour cream.
Serve over boiled potato chunks or rice. Garnish with cilantro and crushed peanuts.
