Garamasala substitute?

[DameDiazepamTheDramaQueen]

Making chicken Katsu but just realised I don't have any garamasala and the recipe calls for a teaspoon . What could I use instead or do I need to Google how to blend garamasala and pray I have all the spices?

Hopefully see not too late but you can see 1/2 a teaspoon of ground cumin and half a teaspoon of coriander powder

Thanks! That's exactly what I did in the end and it came out fine
