Salaam! Non-desis absolutely love samosas and pakoras served with chutney or ketchup - if you're looking for a quick solution, this is a great option. Chick peas salads (chaat style) also work very well. Just combine chick peas with finely diced onions, tomatoes, fresh coriander and add zeera (cumin), chaat masala (shaan's is pretty good), salt, a bit of cayenne, and freshly squeezed lemon juice. Marinated artichokes or chopped/boiled potatoes also make great additions to this salad. (Try to marinate it overnight if you can.) Good luck! I'm sure that whatever you decide will work out well because, from my experiences, people will eat just about anything! When all else fails, opt for a vegetable platter - always a hit. :)
