-- If it's not on your breakfast table, it's most certainly on your Instagram feed.
Avocado toast -- loved by celebrities and health foodies alike -- is most certainly the "it" breakfast food of the season.
Olivia Wilde's posted avocado toast to her Instagram, as has model Karolina Kurkova. Gwenyth Paltrow called the version of the dish that appears in her cookbook It's All Good "the holy trinity of Vegenaise, avocado, and salt that makes this [avocado toast] like a favorite pair of jeans."
And perhaps most flattering, it's been named the "most annoying food on Instagram." And according to Google trends, searches for avocado toast have gone up 31 percent since the beginning of the summer.
In it's simplest version, avocado toast is simply smashed or sliced avocado on whole grain bread with a dash of olive oil and sea salt. Some people like a squeeze of lemon and a dash of red pepper flakes. That's how it's served at New York's Cafe Gitane on Mott Street, where a Les Petits Plats of Avocado, lemon juice, olive oil, chili flakes on seven grain toast costs $7.25. Incidentally, its Cafe Gitane's version that Olivia Wilde loves.
But whether you prefer the simple version or one with a bit more flair, it's a nutritional powerhouse, say experts. Nutritionist Lisa Goldberg told ABC News she had it several for breakfast this week alone, sliced or mashed on Ezekial (sprouted grain) bread.
"I love it for breakfast because avocado has protein and healthy monounsaturated fat, and its also high in fiber so combined with the Ezekial toast it keeps me full for a good 3-4 hours. Plus it's high in other nutrients like Vitamins B, C, E, K and potassium."
