Cook pasta with 1 tsp oil and required water. Drain the water and keep pasta aside.
Cook the chicken well and keep it aside.
For preparing 1st sauce:
1)Heat 1 tsp of oil and add onion paste to it. Saute it well till the oil separates.
2)Add tomatoes and gingergarlic paste to it and saute it well.
When it becomes a paste, remove from fire and keep it aside.(cook this in low flame and if it becomes too hard, add milk to make it a paste)
Now layer it. Add pasta first, then spread the 1st sauce and then the 2nd sauce and spread pasta again. Finally, on top of the pasta, spread the grated cheese and microwave it till the cheese melts. Serve hot.
