Saag/palak paneer is again, a sauce based dish but a lot more milder. Chana masala is also low on spice. Tandoori chicken is not sauce-based, but personally I don’t get too excited about it. Biryani is again no sauce. The last order I had did have a lot of spice, but historically these have been milder than other Indian dishes for me. Certain types of dosas might be up your alley too. This is coming from someone not well versed in Indian food, so I am sure there are more.
