Combine all dressing ingredients except poppy seeds in a large jar with a lid, in a blender, or in a food processor. Shake or mix until completely combined.
Add the poppy seeds and give it another good shake. Set aside and refrigerate until ready to use.
ASSEMBLE THE SALAD:
Arrange spinach in a large serving bowl. Top with strawberries, oranges, avocado, cheese, and almonds. Drizzle some of the dressing over the salad, to taste, and serve immediately.
Notes
Why not make this salad into a main dish by adding some grilled chicken
To keep it vegetarian try adding some hard boiled eggs for extra protein
I used feta cheese for this but a crumbly goats cheese or even blue cheese would also work really well
Instead of toasted almonds, you could use cashews or walnuts
Make sure to use fresh strawberries and not frozen. If you don't have fresh try using another berry
Both the salad and dressing can be prepped in advance just store them separately and toss together just before serving
