Tuna and Egg Niçoise with Roasted Baby Potatoes

Serves 4.


    Tuna and Egg Nicoise with Roasted Baby Potatoes

    Composed, warm salads bring Mediterranean sunshine to the plate any time of year. Sous vide cooking’s precise and steady temperature control in a water bath means sustainable, better-than-canned tuna, is easier than ever. Crisp, tender, and decadent all at once, this French “comfort food” meal is tied together with a zippy lemon-mustard vinaigrette.



    For the protein component, sous vide-cooked salmon or mackerel would be a great alternative to the tuna.

    • 6 Tbsp (90 mL) extra-virgin olive oil, divided

    Preheat oven to 425 F (220 C).


    Prepare sous vide water bath according to manufactureru2019s instructions, and set sous vide cooker to 130 F (54 C) for a well-cooked texture of canned tuna result or 115 F (46 C) for a tender, juicier textured tuna. Add tuna steaks and 2 Tbsp (30 mL) oil to large silicone food storage bag and seal tightly, removing as much air as possible. When cooker has reached temperature, slowly add bag and cook for 30 to 45 minutes, or to manufactureru2019s suggestions. When cooked, remove tuna from bag (save juices), open, and reserve tuna on plate with its cooking oil.


    Add potatoes to large baking sheet and toss with 1 Tbsp (15 mL) oil and 1/4 tsp (1 mL) salt. Roast for 30 to 45 minutes, until tender when pierced with knife. Halve larger potatoes.


    In small jar, shake remaining oil with lemon juice, mustard, garlic, honey, pepper, and remaining salt. Toss dressing with lettuce and tomatoes in large bowl, and add to serving bowls or plates. Flake tuna and divide over salad along with roasted potatoes, eggs, and olives.

    Mussels with Tomato, Saffron, and Fennel

    B12-rich mussels are a very good and economical source of protein and iron. Steamed mussels are a classic way to enjoy seafood—and so is this rich, aromatic broth of tomato, fennel, and saffron. Be sure to allow saffron to fully infuse to get the full flavour benefit, and finish off the dish with the fragrant fennel fronds. Sustainability status Farmed mussels are considered highly sustainable due to their low impacts on the environment. They are easy to harvest, require no fertilizer or fresh water, and don’t need to be fed externally, as they get all their nutritional requirements from their marine environment. Mussel prep Selection: Look for mussels with shiny, tightly closed shells that smell of the sea. If shells are slightly open, give them a tap. Live mussels will close immediately. Storage: Keep mussels in the fridge in a shallow pan laid on top of ice. Keep them out of water and cover with a damp cloth. Ideally, consume on the day you buy them, but within two days. They need to breathe, so never keep them in a sealed plastic bag. Cleanup: In addition to being sustainable, farmed mussels tend to require less cleaning than wild mussels. Most of the fibrous “beards” that mussels use to grip solid surfaces will have been removed before sale. But if a few remain, they’re easily dispatched: grasp the beard with your thumb and forefinger and pull it toward the hinge of the mussel and give it a tug. Afterward, give mussels a quick rinse and scrub away any areas of mud or seaweed, which, with farmed mussels, will require minimal work.
