Go out and fight them. They'll target you, if there's a free path.
Know that in the meadows and the Black Forest, only Boars and Trolls can't be evaded by simply walking away from them, since all other mobs travel at more or less the same speed as you and stop when they hit, and you'll be out of range if you just keep walking, unless you get flanked.
This is also the perfect time to learn to dodgeroll and parry, since these mobs essentially are the weakest you'll meet in the game.
For some aoe, try the stagbreaker and the atgeir.
