Well, I don't know about the Bouillabaisse part but the tastes are very much the same. How incredibly easy to make, and what a taste! This is tortellini taken to a different level; and for a pasta & fish lover like myself, it's a match made in heaven.
How to
Boil some tortellini with optional filling to 'al dente' texture, (approximately 4 minutes). Drain all of the water and add some spiced tomato sauce (basil, garlic) or plain tomato sauce mixed with pesto. Let simmer and add just a splash of cooking cream for a richer sauce base.
Here's where you go nuts with the spices: I used sweet paprika, mixed peppers and mediterranean salt (infused with rosemary among other things).
Taste the soup and adjust the tomato sauce, cream and spices til' you've achieved your desired textures and tastes.
Pour the tortellini + sauce into a bowl, serve with tunafish and garnish with some basil.
Bon Appétit!
