In a skillet over medium heat, add a drizzle of oil and heat it for about 1 minute. Toss in the chopped shallots and cook for 6-7 minutes until they turn golden brown and fragrant. Stir occasionally to ensure even cooking, then drain the shallots on a paper towel and sprinkle them with salt to enhance their flavor.

In a mixing bowl, combine mayonnaise, vegetarian Parmesan cheese, minced garlic, and a pinch of salt. Whisk the ingredients together until the mixture is smooth and creamy.

Choose a clear glass bowl to showcase your 7 Layer Salad's colorful appeal. Begin by adding a base layer of chopped lettuce, followed by a layer of diced red onion. Next, add juicy chopped tomatoes, then sprinkle the thawed peas over the tomatoes. Continue building your salad with diced cucumber, then add the cubed hard-boiled eggs on top for protein-rich goodness.

After layering your ingredients, generously drizzle the prepared dressing over the entire salad. Next, sprinkle shredded cheddar cheese on top, and add the crispy shallots for added crunch.

If serving immediately, your vibrant 7 Layer Salad is ready to enjoy! For later, cover the salad with plastic wrap and refrigerate for up to 2-3 days.
