In a bowl, mix diced chicken with Greek yogurt, turmeric, salt, smoked paprika, garam masala, ginger, and garlic. Let it marinate.
Combine flour and Greek yogurt to form the pizza dough. Knead gently until smooth.
Roll the dough on a floured surface into a pizza shape and form a crust edge.
Bake the base for 5 to 7 minutes at 200°C until slightly firm.
Cook the marinated chicken in a pan over medium heat until fully cooked. Set aside.
In the same pan, melt butter and sauté sliced onion until soft.
Add diced tomatoes, spices, and Greek yogurt. Simmer and blend the sauce until smooth.
Stir the cooked chicken into the sauce.
Spread half of the butter chicken mixture over the pizza base.
Top with grated cheese and sliced red onion.
Bake again until the cheese melts and the crust becomes golden.
Slice and serve warm.
