Heat a large, heavy pan on medium high until scorching hot, but not smoking.
Drizzle olive oil into pan, and heat until shimmery, about 45 seconds.
Add chicken breasts into pan.
Cook 6 minutes on each side, until well browned.
Remove chicken, set aside.
Add onions to pan, and let brown - about 4 minutes.
Add garlic, and continue to brown, another 2 minutes.
Add tequila and cook down, 4-6 minutes.
Add tomatoes, honey, spices, and olives.
Add chicken back to pan, and cook until 165 degrees internal temperature.
If your chicken is very thick, and it takes so long to cook you reduce all of your sauce - never fear - just add more lime juice, a splash more tequila, and/or some chicken stock.
Serve over al dente fettuccine, and enjoy!
Store any leftovers in an airtight container in a refrigerator for up to 3 days.
Can be frozen and re-heated - try to freeze as flat as possible to avoid a giant frozen clump, and add 1/2 cup stock when reheating.
