* I made my own ground chicken here using 4 chicken thighs (with skin) and a food processor. It's very easy to do! Here's a simple tutorial. Ground chicken usually comes in 1 pound - 1.25 pound packages at the grocery store. If that's all you can find, just use that here. Ground turkey or beef would work well too.
** When making chili, I love using a mixture of chile powders to add depth of flavor. If you don't have access to these types of chile powders (or they are super expensive), you could definitely use the spice labeled "Chili Powder." Just keep in mind that chili powders usually have other things mixed in like garlic and oregano, so the end result might taste a little different.
