So many great meals on this thread!
I'm British but have lived in Thailand for 5 years.
I've forgotten how to cook here after initially not having a western kitchen and then just becoming lazy... mostly we eat Thai, sometimes Indian. We buy most of our evening meals from the street/market or have them delivered from local outlets. (This is normal here!!)
Favourites include laab moo, which is minced pork with chilli, lime, and some sort of toasted rice hidden in it (called 'spicy meat salad' on menus but not a salad!), laab moo tod (laab turned into meatballs), som tam (spicy crunchy salad of shredded young papaya, some sort of green bean, carrot, maybe tomato, sometimes tiny dried prawns with the shell still on that you eat whole, in a spicy, limey sauce), tom yum soup (spicy, can be with chicken or prawns, can be clear or have coconut milk added), chicken/prawn fried rice, sundried beef or pork, khao soi (spicy, creamy noodle soup), massaman curry, penang curry, all the curries!
We do still eat pizza, pasta, sushi etc. I've only had 3 roast dinners in 5 years - twice on Sundays at restaurants and once I cooked a Christmas dinner. My kids had no idea what pigs in blankets were!
We can get food of any type here, so if we fancy it we can get it. There's a place nearby that has food trucks with Thai, Indian, Persian, Greek, Chinese, American (smoked meat place, grilled cheese place, burger place), Jamaican, Mexican etc!
Very occasionally I buy something like a tin of Heinz tomato soup, which costs the same as 3 whole meals from the market!!!
