Cook linguine according to package instructions. Make sure to salt the water!
In the meantime, cut the tops of the mushrooms off and place in a bowl. You can cut small pieces of the stems as well, they will also look clam like. Toss the mushrooms with the 2 tsp. of olive oil and the kelp powder.
Heat the remaining 1/4 C. of olive oil in a pan on medium high. Add the garlic and reduce heat slightly to about medium. Saute garlic for a minute, then add the mushrooms.
Saute for another minute or so, then add the white wine. Reduce heat to low, and simmer for 5-10 minutes to cook off the wine a bit and reduce it.
Throw the parsley into the sauce and turn off the heat and stir. Taste and season.
Once the linguine is done, drain and toss with the sauce. Taste and adjust seasoning, top with fresh lemon juice if you want, and maybe some vegan parm?!
