Tikka Masala sauce is a creamy and spicy tomato-based sauce. Tikka Masala was born as a fusion dish, to accustom the British to Indian curries. The fact that it is tomato-based has made it a perfect substitute for many dishes. Some examples so far that I have used a base of Tikka Masala sauce are:
Tikka Masala Chicken over pasta or as a wrap or as a sandwich or over rice
