I suggest you break dishes into 5 groups of 3: soups, starters, mains, deserts and baking. 
For example: 
3 soups: supa topcheta(meatball soup), bob chorba(beans soup) and tarator;
3 starters: gyuvetche, chushki v domaten sos(peppers in tomatoe souce) and surmi;
3 mains: musaka, kiufteta and gyuvetch;
3 desserts: mlqko s oriz(sweet rice with milk), makaroni na furna(sweet mac&amp;cheese, oven baked), biskvitena torta(biscuit cake);
3 bakes: banitca, milinki, pitka;

I'm sure the other readers will come up with more dishes you can choose from, these here were only for example. :) 
Once you decide on the dishes you'll be able to plan your shopping.
As for joining - I think moust of us are up for it. :D
