French stuffed baguette?

So this was about 7 years ago, I was in Paris about 3-4 blocks from the Eiffel Tower before going to a patisserie for a snack. It looked exactly like a baguette, except it had ham and cheese stuffed into it, not after it was baked but closed on all sides of the bread like it was put in before baking.

This is the weird part. Both my ex and I distinctly remember it being called “flube” or some variation of that. It might have been spelled “flûbe”?

Only because for the rest of the trip we couldn’t stop joking about it. Have I completely hallucinated this? I can’t find anything remotely close on google but maybe a Parisian can help me out here? It was so simple and amazing. I don’t remember the shops name at all…

Thank you!
