This is a modified recipe of "Mussels à la Buzara", trying to replicate a dish from http://www.dubravka1836.hr/

2 lbs mussels, scrubbed and de-bearded; dispose of any mussels with shells that stay open.
2 medium tomatoes, diced
¼ cup breadcrumbs
4 garlic cloves, minced or sliced
1 medium onion, finely chopped
1 cup dry white wine
½ cup parsley, chopped
olive oil
Salt and pepper to taste
