At the start of every year, and indeed at most other times of the year, there is someone who wants to eat salad. I was asked to do a posting about salad which I took to be about salad with lettuce. So, let us eat lettuce!
Cosme: “Col” salad at Cosme. This large (larger than most main courses) salad is served on a ten inch wide plate and is large enough for a main dish or to be shared as an appetizer. It is listed as an appetizer on the menu at Cosme. The salad has raw shredded red cabbage, alfalfa, cashews, hearts of palm, artichoke, cherry tomatoes, lettuce, avocado, and the dressing is a yogurt based dressing so you feel healthy when eating it.
Matria: Also has a decent salad. It’s pretty and actually makes you want to eat salad.
Osso: Although Osso is a steak house, there is a selection of salads including an attractive wedge salad (in real life, in the close up above, the wedges rise like the Andes covered in mint green and dusted with bacon and candied pecans). The second salad mentioned, “salad #3” contains tiny deep fried cheese balls. I recommend keeping the dressing on the side, and foregoing the song and dance of the waiter pouring and tossing, so that you can enjoy the fried cheese “croutons”. The salad is called #3 because on the old menu, it was the #3 (at least, I think that’s why).
Cafe Mozart: Located in San Borja, this cafe has an all-you-can-eat salad bar. The salad bar has a full selection of cooked items including pasta salads and many other salads to put in the salad.
La Mora: They have several salads. They also use a classic European mustard vinaigrette. Because the olive oil is whipped/emulsified in, the dressing has the thickness of an aoli (mayonnaise in plain language).
Cafe A Bistro: The head salad is like an iceberg wedge salad, but you get all and not only the wedge (the photo doesn’t do the salad justice as the salad is more impressive when viewed in profile).
Antica: One of the salads uses butter/bib lettuce and has wedges of oranges among other things making it a decent salad.
La Panka: This chain restaurant has large salads. The one below is with roasted veg and chicken. The salad is the size of small hot tub.
La Linterna: Also has a decent house salad with ham and pecans.
Taller Razeto: Has good salads (melted cheese on a bed of lettuce in the photo below), but the restaurant is out in La Punta so not a daily destination unless you live there.
Pardos Chicken: Has a lettuce salad but I like their “cooked salad” with cooked carrots, beets, beans, and avocado. But, we were talking about lettuce.
Poke Pacifiko: As you can order exactly what you want, I imagine you can make your own salad. I’m sure you can get it without fish.
Plus, I would guess that most of the vegetarian and vegan restaurants have lettuce salads.
Vegan food in Lima? Yes, apparently. I asked some vegans for their list of places to eat. This blog posting is cribbed off of their list (though, I think you can ask at any place and then can probably make it vegan for you.)
San Borja:
Poke, pronounced “poh-key”, is a Hawaiian raw fish salad, usually made with tuna. In Hawaii, this salad is made with raw tuna cubes, soy sauce, onion, garlic, sesame seed oil, and chili flakes. With endless variations.
Poke is similar to carpaccio (Peruvian style from Santo Domingo above), tartare salad (the one in the photo has a poached egg on top), or donburi (similar to donburi, 
Here in Peru, I’ve had poke in Jeronimo’s (see photo above)and I expect to see the appearance on many more menus in the future. Lima has all the necessary ingredients: fresh fish, Japanese cultural influence, and a flourishing gastronomic scene.
