Reincarnated Witch’s Carefree Gourmet Journey

The protagonist, Marie, is a disappointing young lady who has always been compared to her more capable sister.
After her engagement to a prince is broken off, she is banished from the ducal house. The shock triggers the return of her past life memories.
She used to be a witch named “Lovmarie,” who defeated the Demon King and saved the world, becoming a revered figure as a result.
Regaining her memories and powers, Marie becomes free from her broken engagement.
During her journey, she meets a young beastman who used to be a chef and decides to travel with him in search of gourmet food.
“Amazing! You took down the dragon in one shot! You’re a lifesaver!”
“Don’t get me wrong, I just wanted to eat dragon steak.”
“You’re so tsundere! (Misunderstanding)”
Meanwhile, the ducal house and prince who banished Marie realize that in this world suffering from magical decline, she is the only magic user.
They later panic when they realize she’s the reincarnation of the witch who saved the world, but it’s already too late.
