It sort of depends on if you have Mexican ingredients available. I am lucky to be living in Glasgow, where we have a 'Mexican deli' (that's what the shop calls itself) and also a Whole Foods, which stocks a few Mexican products. We also have a couple of really good burrito shops, so I no longer feel that I 'miss' Mexican food, as i can pretty much have it whenever i want.
If you don't have anything near you and don't mind shopping online, try:

I don't use recipes... i just cook by instinct and trial-and-error!
Last night we had a sort of chicken chilli... chicken, white beans (i normally use haricot, but used butter beans last night), green chilli salsa, chicken stock.
This morning's breakfast was migas... scrambled eggs with corn tortillas (fried and shredded up and cooked in the eggs), with grated cheese, green chilli salsa and bacon.
When I was making the chilli last night, i set aside some of the chicken, which I will spice up and make chicken tacos for tonight, as I've got plenty of corn tortillas left.
