The night before, marinade the chicken breast. Refrigerate overnight.
Begin cooking by cooking chicken breast in a skillet, then reserve. Cut into small pieces.
In the same pan, bloom the spices, tomato paste and garlic ginger paste in some oil.
Add water and cream to the pan, and stir until combined. Simmer briefly.
Preheat the oven to its highest temperature, with the baking sheet inside.
Lay down a tortilla on parchment paper, cover lightly with sauce, then with the other toppings.
Transfer the pizza onto the baking sheet using the parchment paper. Broil for several minutes on the highest rack for several minutes, or until cheese is melted.
Remove from oven, allow to cool completely, and cut into slices. Repeat with the other tortilla pizza, then serve.
