Any ideas for replacement for salami?

Closest thing I've found that comes close to a replacement taste wise and that isn't pork is turkey pepperoni. I use it in my pasta salads, it's a great replacement.

Agree on the idea of using tuna! I’d drain and toss it in a little of the vinaigrette, then add it to the farro salad (after it’s broiled) with the tomatoes and arugula. Or you could cook virtually any type of protein — chicken breast, steak, tilapia, shrimp — and toss it in at the end!

Or other fish (whether canned or poached). Anchovy (fillets), smoked mackerel, sardines, salmon, cod.
Or Parmesan (cut from a wedge).

Hi J! I think tune or a soft boiled jammy egg would be pretty nice with these ingredients.
