• Before starting, preheat the oven to 450°F. 
• Wash and dry all produce.
• On a parchment-lined baking sheet, arrange flatbreads. (NOTE: It's okay if they overlap.)
• Bake in the middle of the oven for 3-4 min per side, until golden.
• Set aside.

• Meanwhile, cut tomato into 1/4-inch pieces.
• Halve, peel, then cut half the onion into 1/4-inch pieces (whole onion for 4 servings).
• Zest, then juice half the lemon. Cut remaining lemon into wedges.
• In a large bowl, whisk together 1 tsp (2 tsp) pesto, 1 tbsp (2 tbsp) lemon juice, 1/4 tsp (1/2 tsp) sugar and 1 tbsp (2 tbsp) oil. Season with salt and pepper. Set aside. (NOTE: This is your dressing.)

• Pat salmon dry with paper towels.
• To another large bowl, add lemon zest, salmon and 1/2 tbsp (1 tbsp) oil. Season with salt and pepper, then toss to coat.

• Heat a large non-stick pan over medium-high.
• When hot, add 1/2 tbsp (1 tbsp) oil, then onions. Cook for 2-3 min, stirring often, until tender.
• Transfer onions to a plate and set aside.
• To the same pan, add 1/2 tbsp (1 tbsp) oil, then, salmon. Pan-fry for 3-5 min per side, until browned and cooked through.**
• When salmon is done, break salmon up into large pieces, removing and discarding skin.

• Working on the prepared baking sheet, spread remaining pesto over each flatbread.
• Top with salmon, onions, feta and half the tomatoes. 
• Toast assembled pizzettes in the middle of the oven for 2-3 min, until warmed through.

• Cut cucumber into 1/4-inch rounds.
• To the large bowl with dressing, add baby spinach, cucumbers and remaining tomatoes. Toss to coat.
• Divide pizzettes and salad between plates.
• Dollop or drizzle yogurt sauce over top of flatbreads. 
• Squeeze a lemon wedge over top.

If you've opted for salmon, pat salmon dry with paper towels. Season in the same way the recipe instructs you to season the shrimp.

To the same pan the onions were cooked in, add 1/2 tbsp (1 tbsp) oil, then, salmon. Pan-fry for 3-5 min per side, until browned and cooked through.** When salmon is done, break salmon up into large pieces, removing and discarding skin.
