Heat oil/ghee in a large dutch-oven or stock pot over medium heat.
Add in your onions, peppers, and garlic, then sauté for about 3-4 minutes.
Stir in your uncooked brown rice, and saute for about 2 minutes, then carefully add your stock/broth, sea salt and pepper. Allow everything to simmer covered over low heat, until rice is almost done, about 35 minutes.
Once your rice is tender, stir in your crushed tomatoes, red pepper flakes, and coconut milk.
Continue to cook for 5-10 minutes to allow the flavors to develop.
Add in your fresh lemon juice, and raw shrimp and stir for a couple of minutes until just cooked through. Shrimp will cook fast, so make sure you don't over cook them.
Season your delicious soup with freshly chopped parsley, and lemon wedges, then serve hot.
