A couple of easy ones I've recreated - toast small rounds of wholemeal baguette while sauteeing a mixture of mushrooms in olive oil and garlic then spread them onto the the toast; grill asparagus dipped in olive oil and balsamic vinegar then wrap in smoked salmon or cured spanish ham; marinade a mixture of black and green olives in olive oil, garlic and crushed chilli flakes; make small meatballs with beef mince, garlic, breadcrumbs, oregano, paprika and black pepper; do cheats empanadas with tuna, tomatoes and olives using small pitta breads...probably others I've forgotten too!
