Like middie, we have never celebrated lent. But it sounds like a fine time to try out some recipes.
Just some ideas, and I will include cheese and seafood here, please excuse me if they are not tolerated.
Falafel sandwiches.
Hummus.
Baba ganoush.
A hot and sour soup without veggie broth.
Sesame (peanut butter) noodles.
Any other veggie soup, such as pasta fagiola, maybe with a sandwich.
Lobster rolls.
Shrimp salad.
A frittata, with seafood and cheese, or not.
Omelets, including pizza omelets, served with fried taters and maybe some fruit.
Fried rice, with shrimp or tofu.
Egg foo yung (yes I know it is not Chinese, but it is tasty).
Stuffed mushrooms or clams or oysters.
Stuffed tomatoes, or peppers.
Just a few ideas.
When I was a kid a lot of my friends were Catholic and they hated Friday meals (that was during the time meat was outlawed on that day).
We, not of that religion, usually enjoyed eating the seafood, it was always fresh and readily avialable.
Could easily live without meat for quite a while, although I doubt I ever would.
I guess my point is there is a whole lot of other good stuff out there.
