Hello Lourdes. That is a wonderful idea, as traditional Olivier salad is quite versatile and adapts very well to lighter supermarket alternatives.
Here are several simple and accessible substitutes you can try depending on your preference:
1. Poached Skinless Chicken or Turkey Breast: If you still consume poultry and simply want to avoid processed deli meat or fatty beef, poaching a chicken breast with a bay leaf and a pinch of salt is the classic light choice. Once cooled and diced, it blends naturally with the potatoes and peas while keeping the fat content low.
2. Canned or Sautéed Mushrooms: For a completely meat-free version, diced button mushrooms (champignons) are excellent. If you use fresh ones, dice and lightly sauté them until their moisture evaporates. If using canned mushrooms, simply drain them thoroughly. Their earthy flavor and tender texture mimic the bite of meat beautifully.
3. Firm Tofu: Plain firm tofu is widely available in most supermarkets. Press out the excess liquid with a paper towel, cut it into small cubes matching the size of your diced carrots and potatoes, and mix it in. Tofu readily absorbs the flavors of the dressing and the pickles.
4. Canned White Beans: Drained and rinsed cannellini or navy beans add wholesome protein and substance. Because of their mild taste and soft texture, they pair seamlessly with the green peas and root vegetables.
5. Drained Canned Tuna (in Spring Water): If you enjoy seafood, canned chunk light tuna drained of all liquid creates a very refreshing, lighter variation reminiscent of traditional picnic salads.
Chef tip for an even lighter salad: You can replace half (or all) of the traditional mayonnaise with plain low-fat Greek yogurt, seasoned with a small teaspoon of Dijon mustard and a splash of pickle brine to maintain the signature creamy, tangy profile.
I hope this helps you prepare a lovely and satisfying dinner!
