In the spirit of community we've been invited to a neighborhood Shrove Tuesday pancake dinner & asked to bring a side. I'm Jewish & need some help!

Thanks to all! Wonderful and interesting suggestions. I'm still debating which of those suggestions I should use for the party. Next month the neighborhood is doing a seder. I'm in like Flynn!

A quiche or frittata would go nicely with pancakes. You could bake them in a muffin tin so they are bite size and feel more like a side dish.

Yes, pancakes with a side of pancakes doesn't sound like the greatest idea (though my kids would disagree.)

Depending on the type of pancakes, you could do a salad as Maedl suggested - this time of year, this might go well: some kind of greens (e.g., arugula) with sliced oranges (or blood oranges,) black olives and thinly sliced red onion. Or homemade apple or apple-pear sauce, or fruit chutney.

If you are supposed to bring a side dish, I wouldn't bring more pancakes. Depending on what kind of pancakes are being served, perhaps a green salad or citrus salad (oranges, pineapple, blueberries and maybe a strawberry or two for color?) would complement the pancakes.

And for historical variety, consider making cheese pancakes...what Jews made for Hanukkah before the potato made it to Europe.

A pancake dinner? I'm Jewish too, and I would bring Latkes.

A couple of ideas: My Jewish friends at work would sometimes bring in Hamentaschen for Shrove Tuesday, as the two holidays often occur close in time. After all that Babka discussion, Babka is nice too! Shrove Tuesday is all about using up "rich" ingredients, like butter, sugar, and eggs, prior to a period of fasting. Be inspired by what you might make when you clean your pantry in advance of Passover, as it's a similar tradition (cheesecake with those graham cracker crumbs, for example...). Another popular dish for Shrove Tuesday are homemade donuts, cousin to sufganiyah. Feel free to share your family's traditions; this is how we build bridges! And have fun!

No problem. Bring a tray of potato pancakes! Or make some fun toppings to accompany the pancakes, chocolate sauce, whipped cream, fruit, etc. Or a big fruit salad or deviled eggs.
