Re-planning your dinner when you've eaten a really bad lunch

Ughh,,, today I at some really bad food that looked like this

What do you do when you have just gone to try a new restaurant where everything that you've ordered shows up looking like this, just floating in oil and cream ?
I can see one source of much of the fats in Indians' bellies, it is the type of Mughlai foods we all grew up eating. I remember eating dishes like these, with dum aloo, daal makhani and butter naan. Yum!; but no more ..... We have a diabetes explosion. Boom !
So how did we compensate after at the 21 Gun Salute :
Since this lunch, at dinner we eat mostly live foods, tomatoes, cucumbers, carrots, with hummus and some gluten free bread (can substitute with whole grain or whole wheat bread). The emphasis of this article is that in managin disease through food you have to PLAN your food; but you still need to live a life and if you end up going to a bad place you have to remember to make up for the bad food you just ate. 
I do feel better now and I have learnt what to order next time I end up at such a place (kababs). Some notes if you have to eat there :
1) We skipped as much of the gravy as possible at the restaurant
2) We were eating Pudina Parathas which were whole wheat versus the white flour in naan.
