Preheat the oven to 350 degrees F. Line a sheet pan with parchment paper.
Combine the breadcrumbs, almonds, lemon zest, pinches of kosher salt and black pepper and 1 tablespoon olive oil in a small bowl.
Spread the breadcrumb mixture across the prepared sheet pan. Bake in the oven until it is golden brown and toasted, about 10-12 minutes.
Cook the orzo in salted boiling water until al dente according to package instructions. Drain and rinse with cold water in a colander or strainer.
Combine the orzo, navy beans, olives, sun-dried tomatoes, red onions, baby spinach, parmesan, parsley and toasted breadcrumbs in a large bowl.
To make the vinaigrette, whisk the garlic, mustard, 1/4 teaspoon kosher salt, 1/4 teaspoon black pepper, lemon juice, vinegar and olive oil in a small bowl.
Drizzle the vinaigrette into the salad, tossing to combine.
