Grilled Portabella Muffuletta Recipe

Grilled Portabella Muffuletta
Full disclosure: I have never had an actual muffuletta before, only vegetarian versions. So I can’t say, “Hey guys, this tastes just like a real muffuletta!” I really have no idea if it does. But it does taste just like a vegetarian muffuletta.

I decided to try to make this after I had a portabella muffuletta at Sandwhich in Chapel Hill. You know how sometimes you get something at a restaurant and it’s so good that you’re still thinking about it days later? Yeah, that happened. I figured that it would be easy enough to whip up at home–the grilled portabella was a no-brainer so all I really had to figure out was the olive salad. (If you’re a mushroom hater, grilled zucchini or eggplant can be used in this recipe instead of portabellas!)

Olive Salad
Although muffulettas are named after the bread they’re made on, to me, it’s the olive salad that makes the muffuletta. So this is my version. As my husband helped me chop things for this (oh, and there’s a lot of chopping!), he wondered how something made with so many nasty jarred ingredients could taste so good. Well, it just does! (And for the record, I love olives and marinated artichoke hearts and capers–Chris thinks they’re gross, though.) The longer you let the salad sit in the fridge, the better it tastes, so don’t hesitate to make this a day or two in advance.

Finding authentic muffuletta bread in Raleigh was a little bit difficult. The first time I made this, I used a round loaf of bread, but muffuletta bread is fairly flat and this bread was tall and fluffy so it just didn’t work. So then I switched to ciabatta. It doesn’t have the nice round shape of real muffuletta bread, but it’s flat and not too bready. Although anyone from New Orleans is probably giving me the side-eye right now, you could also put this on sourdough bread, Kaiser rolls, whatever. If you use slices of bread or rolls, instead of making one big sandwich, just make four individual sandwiches with a mushroom on each.

These vegetarian muffulettas are very picnic friendly. You can cut them up, wrap ’em, and let them sit in the fridge for up to a day. (I store mine upside down so the bread on the bottom doesn’t get soggy.)

Nat – you must have forgotten that our Dad used to make a huge muffuletta sandwich for dinner every once in a while. I dont’ remember exactly what went on it, but I do remember that the combination of flavours and ingredients was a bit too strong and sophisticated for my taste buds! Now that my tastes have grown up a bit, I think I would love your vegetarian version (and I would probably prefer it on ciabatta bread too)!

Yum! This sounds so doable.

Just out of curiosity, do you recommend Sandwhich? I’m at Carolina, and I usually try to drag my boyfriend to Med Deli, but he isn’t a fan. This might be a great alternative!

Yes! We go there pretty much anytime we’re in Chapel Hill. They’ll make just about anything on the menu vegetarian, which is nice. And they have harissa ketchup. 🙂

Oh I’ve had quite a few muffulettas and this looks like the real thing, but of course it’s missing the meat. However, I love the substitution with the grilled portabella. I love grilled portabella burgers so I know I would love this one! Great sandwich!

Oh I haven’t had a muffuletta since I moved from New Orleans– and that’s almost 10 years ago! This version sounds amazing. It also looks *perfect* for the picnics we are having this weekend, which be at the Jazz Fest in Five Points neighborhood in Denver. Jazz + muffulettas?! Yup, that will work!

Had this for dinner tonight. Yum. I am really glad I found your blog; I have made three of your recipes in the past few weeks and all three were very delicious. I am new at being a vegetarian and I am really grateful for all the great recipes you post.

Yummmmmm! I love olives of all kinds and I love artichoke hearts! The olive salad sounds amazing. I’ll definitely make some to have in the fridge for sandwiches and stuff throughout the week. Thanks for sharing! xo
