Seared tuna with avocado salsa verde is a super-simple summer dish that is elegant enough for entertaining, but quick enough for weeknight dinners.

Step 1

Combine cilantro, garlic, lime juice, red pepper flakes, ¼ tsp. each of the no-salt substitute and black pepper in a blender. Blend, gradually pouring in all but 1 Tbsp. of the olive oil, until mostly smooth.

Step 2

Transfer mixture to a bowl; gently toss with diced avocado.

Step 3

Heat a grill pan or cast-iron skillet over high heat.

Step 4

Rub tuna steaks with reserved 1 Tbsp. oil; sprinkle with remaining ½ tsp. no-salt substitute and ¼ tsp. black pepper.

Step 5

Cook the fish for 3-4 minutes each side.

Step 6

To serve, slice tuna steaks and spoon avocado salsa verde overtop.
