01 - Rinse quinoa under cold water until water runs clear. Combine quinoa, water, and 1/2 teaspoon salt in a medium saucepan. Bring to a boil over high heat, then reduce to low, cover, and simmer for 12-15 minutes until liquid is absorbed and grains are tender. Remove from heat, fluff with a fork, and let cool completely to room temperature.
02 - In a large mixing bowl, whisk together olive oil, lemon juice, honey or maple syrup, Dijon mustard, salt, and black pepper until emulsified and smooth.
03 - Add cooled quinoa, strawberries, cucumber, red onion, basil, and mint to the bowl with dressing. Gently toss until evenly coated, being careful not to mash the strawberries.
04 - Top with crumbled feta and toasted nuts just before serving. Serve chilled or at room temperature. Can be made ahead and refrigerated for up to 2 days.
