"Create a dairy-free, wheat-free, and corn-free version of a dill pickle ranch potato salad inspired by a classic dill pickle ranch potato salad. Keep it beginner-friendly, quick/easy, and suitable for a household of 3. Use minimal processing, low-inflammation-friendly ingredients, and avoid gluten, dairy, nuts, shellfish, soy, sesame, and corn. Use imperial units only. Include a creamy ranch-style dressing made without dairy or corn-derived ingredients, and keep the dill pickle flavor prominent. Provide ingredient substitutions and clear steps."
