I've sung the praises of Trader Joe's Everything but the Bagel Seasoning ad nauseam at this point but I'll continue to do so. With a winning combination of toasted sesame and poppy seeds, minced onion, dried garlic, and sea salt, this holy grail goes with pretty much anything.
You can put it on eggs, avocado toast, dips, pizza, Bloody Marys, Greek yogurt, and, heck, even actual bagels. It makes my plain toast taste like something I ordered from a restaurant and coming from someone who is a very mediocre home cook, I can't ask for more.
