Wash and dry greens, tear into bite-sized pieces, arrange in a serving bowl
Slice or dice meats, shrimp or tofu to taste
Prepare the dressing: Combine 3 parts oil to 1 part vinegar or lemon juice, or mix plain yogurt or mayonnaise with mustard and sweetener. Add minced garlic, salt and pepper and spices to taste.
Toss greens with dressing or keep on the side. Arrange proteins and additions on the greens. For tender greens, choose additions that won't weigh down and crush the greens. Sturdier greens (romaine, butter lettuce) can take weightier additions. Choose what tastes good together to you.
If the household has different preferences, keep controversial toppings and dressings separate and let people add what they like to their own serving.
