Combine the homemade cajun seasoning spices in a bowl.
If your shrimp aren’t already cleaned, go ahead and de-shell and de-vein them. Pat dry, coat in a drizzle of olive oil and 1 tbsp of the cajun seasoning, and a pinch of salt. Toss to coat and place on the side.
In a large skillet or sauté pan over medium heat, add a drizzle of olive oil. Once hot, add in the speck. Cook for 4-5 minutes, until the fat has rendered down
Toss in the shallots and garlic. Sauté for 2–3 minutes.
Add the rest of the cajun seasoning and bloom the spices for 2 minutes, stirring frequently.
Pour in the white wine and let it simmer for 5–6 minutes.
Add the chicken broth and collard greens. Cook with the lid on for 10 minutes over low heat or until the greens have wilted and are tender.
When the greens are ready, pour in the heavy cream, and butter and stir to combine.
Add the shrimp to the pan and cook for 2–3 minutes per side, or until they’re just cooked through—pink, opaque, and slightly curled.
To serve, scoop a generous amount of grits in a bowl and top with the cajun shrimp and collard greens.
