By far the most important thing is to make your own refried beans. Super easy in the crock pot. Soak pinto beans overnight then into the crockpot, keep covered with 1/2 inch of water, 6-8 hrs on high, mash with potato masher, add a little leftover bacon grease you keep in the freezer, and salt to taste. If they are too soupy, take the lid off and cook some more, stirring once in a while. Canned refried beans are god-awful.
I haven't used the packaged taco seasoning for anything in ~30 years. You probably have all the ingredients individually. Chili powder, salt, garlic powder. onion powder, cumin, oregano, cayenne, etc. Make your own and customize to your liking.
And, maybe try a different salsa..
