Use Cajun / blackening season to amp up the flavor of simple ingredients, like salmon, rice, and green beans. Smarts: Take advantage of frozen green beans outside of the summer green bean season.
Preheat oven to 500F / 260C. Spread green beans out onto a sheet pan. Cover tightly with foil and then ‘steam’ in the oven for 5 minutes. Toss with olive oil and Cajun spice and roast for another 15 to 20 minutes, rotating and stirring beans once midway through. Depending on your oven, you may want to roast longer for crispier green beans - they should almost feel like green bean fries. Finish with salt and pepper fresh out of the oven.
Heat a saucepan or Dutch oven or non-stick pot over medium-high heat for rice and beans. Pour in coconut milk, garlic, bay leaves, and Cajun spice. Bring to a simmer and then add rice, chicken stock, and salt. Cover and bring to a boil and then simmer for 15 to 20 minutes, until rice has absorbed all the liquid. Fold in beans. Season to taste with more salt and spices.
Heat a skillet or non-stick pan over medium-high heat. Add second half of butter to pan. Tip pan to evenly distribute butter. Place seasoned salmon fillets flesh-side down and sear on each side for 2 to 3 minutes. Lower heat to medium, cover pan loosely with foil and cook for another 4 to 8 minutes, depending on thickness of salmon and desired level of doneness.
Enjoy salmon with lime wedges and rice and green beans on the side.
