What is a cooking style that uses ingredients and techniques from more then one regional cuisine in single dish?

The cooking style you're describing is called fusion cuisine.

Here's a breakdown:

* Fusion cuisine is a culinary style that combines elements of two or more distinct cuisines, creating something entirely new.

* It involves blending flavors, ingredients, cooking techniques, and presentation from different cultures.

* Examples include:

* Thai-Mexican: Pad Thai with a lime and cilantro slaw

* Japanese-Italian: Sushiritto (sushi burritos)

* Indian-French: Tandoori-spiced chicken with a creamy saffron sauce

* Chinese-American: General Tso's chicken

Fusion cuisine is a modern culinary trend that celebrates the diversity of global flavors and encourages culinary experimentation.
