Heat almonds and sugar in a skillet over medium heat, stirring often so the sugar melts evenly. Continue cooking until nuts are coated and lightly caramelized. Spread them out to cool so they stay crunchy.
In a large bowl, add arugula and season lightly with salt and pepper. Toss in strawberries, avocado chunks, goat cheese, and pistachios so flavors distribute evenly.
Combine vinegar, lemon juice, honey, mustard, garlic, salt, and pepper in a bowl. Slowly whisk in olive oil until smooth and emulsified.
Pour dressing over salad just before serving and gently toss everything together. Sprinkle candied almonds on top and serve immediately for maximum freshness and crunch.
