What to do with sea beans?
Well, not only have I never cooked with them or tried them, but I never heard of them before. So here's what I found on Google to satisfy my own curiosity, fwiw.
The Seattle Times had the best overall info with a nice picture
Snappy, briny 'sea beans' bring the beach to your table
Hormel also has a nice overall description and says ...
:"The crisp textured bean stems and leaves can be eaten raw, steamed, boiled, sautéed, or stir-fried to add a unique presentation for fish and seafood dishes. They are often served fresh in salads or can be boiled and served with melted butter for dipping"
A few web recipes ...
