This tray may seem more involved than your standard vegetable crudités platter, but I assure you it’s worth the extra effort! If you want to speed things up, you can use multiple pots to cook the shrimp, eggs and baby potatoes. But there’s no need to. Make sure to leave the making of the aioli for last since a skin can form on the top. It’s no big deal, though: just whisk again right before serving. If you’re low FODMAP, you can omit the garlic. You should still be able to tolerate the scallions in modest quantities.
