In these times of culinary substitution, perhaps it isn’t surprising that people are swapping in seaweed snacks for chips, and puffed lily seeds for popcorn. While eating greens has always been a goal, looking to the sea for them is a creative and tasty trend we’re seeing now.

According to nutritionist and registered dietician Eliza Savage, “fish, seaweed, kelp, and other items from the sea contain an abundance of nutrients. Seaweed and kelp are great vegetarian sources of protein, fiber, and minerals.”

Of course, the new items must, first and foremost, taste good. Here are some creative ones to try—beyond just plain, dried seaweed.

Tempura Seaweed Snacks

Seaweed snacks—crunchy pieces of dried seaweed dusted with salt and other seasonings—have been around for some time, but Nora Tempura Seaweed Snacks open up a whole new category of tastiness. That’s because the seaweed is dipped in wheat flour and tapioca starch before hitting the fryer, resulting in a delightful crunch. There’s only a hint of that ocean taste here. This snack also brings the added bonus (or curse?) of being addictive; it’s possible to eat an entire bag, either in the original or spicy flavor.

Water Lily Pops

Taali Popped Water Lily snacks are made from the seeds of the water lily. This superfood snack is available in different flavors, from Himalayan Pink Salt to Tangy Turmeric. They have the texture of popcorn—without the annoying kernel that gets stuck in your teeth—or of an airy cheese puff (gasp).

Kelp Noodles

For the wheat/gluten/carb-averse, kelp noodles are an alternative that are 100% grain free. These “noodles” from the natural-food company Gold Mine are literally just strands of kelp from the ocean, cut into the shape of spaghetti. They don’t need to be cooked, but if put into broth, they will absorb the flavors nicely. The noodles by themselves have a bland taste, and the texture is much chewier than pasta noodles.

Savage says kelp, a type of seaweed, is a “good vegetarian source of iron and is chock-full of minerals, especially iodine, which is critical for thyroid function.”

Salted Egg Fish Skin

A salty and crunchy snack hits the spot in delicious ways. Enter crispy fish skin, which delivers crunch and salt with nutrients, too.“Having a snack that combines protein and some healthy fat”­ is a good thing, Savage says. And salmon is a good source of Omega-3 fatty acids, among other nutrients.

Epi’s Salted Egg Fish Skin snack is supercrispy and has an almost buttery consistency, like the inside of a soft-boiled egg.

Kelp Jerky

We’re calling it now: Kelp jerky is on track to become the next kale chip. Eating less red meat is better for the planet, environmental activists say, which is the idea that Akua, a company that recently debuted jerky made from kelp instead of beef, is banking on. According to its website, the sea-greens-sourced product is nutrient-dense, high protein, and sustainably harvested. It’s available in three flavors: sea salt, BBQ, and High Thai’d (coconut and turmeric).
