Orange Crunch Salad

1 head romaine lettuce
1 (10oz) can mandarin orange sections, well drained
1/3 c slivered almonds, slightly toasted in oven
1 avocado, cut in bite-sized pieces (optional)

Toss with poppy seed dressing.

I like to add spinach to this salad for variety (and iron). A yummy alternative to toasting almonds is caramelizing them.
