korean bbq! oh my god, there's a place not too far from me that has ayce for only $20, and it is truly my favorite restaurant. i KNOW my family is sick of me asking to go to this place, but i just cannot get enough!
Chicken. I'd say rice, but rice alone isn't fun to eat. So I'd go with my favorite meat of all time. Fried roasted, boiled, grilled, etc. Chicken is life.
For me it's pad Thai. Orange chicken is my favorite food overall, but I get sick of it if I have it often enough. Pad Thai on the other hand I'm always up for eating. I crave it often and it feels like there's so many different ways to cook it. I can't think of two Thai restaurants that cook it the exact same way.
I honestly can't eat something daily for my whole life without wanting to switch out and try something new...and plus, think of what happens to your body!
But to answer this question, I'd go for a chicken-and-rice dish.
