Yea that’s why I prefer vegetarian over vegan. A ton of the classic vegetarian dishes that are amazing rely on dairy and other animal products that aren’t directly meat. From simple things like quesadillas to sopes vegetarianos and enchiladas.
It’s all about spices though, I’m dissaponted in that restaurant. Mole Poblano is quite literally all spices and chilis.
Out of curiosity I googled vegetarian Mexican recipes and I’m a bit disappointed there was non of the classics that I cook on the top pages. It’s a lot of nuvegetarian recipes, which there’s nothing wrong with but they all seemed sorta samey.
