Salad of Roasted Potatoes and Mushrooms on Spinach W/basil Aioli

“This is a salad in the style of Provence (Southern France, on the Mediterranean). Aioli is a garlic mayonnaise popular in that region, often served with vegetables and fish. Homemade mayonnaise includes raw egg yolk, which brings a small risk of salmonella contamination. You can now get pasteurized eggs in stores, or if you are very concerned, you can add the garlic, basil, lemon juice, and seasonings to commercial mayonnaise, though it won't be exactly the same.”
