Alliaria petiolata is a pretty common herb in Europe (at least here in Germany) and it is related to mustard, cabbage plants and rapeseed. It does have a garlicky smell, but I wouldn’t really use it as an replacement to real garlic. Garlic plants are not related to it at all and are very different. Allium ursinum (wild garlic) on the other hand is also pretty common here and actually tastes like garlic.
Is it just a type of mustard plant or is it a garlic and mustard sauce/mix?
