For the mussels, clean the mussels and discard those that remain open. Peel the garlic and press it with a press.
Heat some oil in a pot and fry the garlic in it. Set aside a spoonful of the garlic oil. Add the mussels and deglaze with the white wine. Salt and pepper vigorously and simmer covered for 10 minutes until all the wine has evaporated and the mussels have opened.
Slice the bread and fry on both sides in a pan with the garlic oil and chives set aside.
Serve with lemon wedges.
