In a small pan, place the chopped walnuts and the cardamom. On medium-low heat, toss the walnuts and cardamom for a minute until the walnuts start to brown and smell fragrant&toasted. Make sure the walnuts don't burn, so stir constantly to ensure even toasting. Remove and let cool.

Meanwhile, clean the spinach and cut into suitable pieces without crushing.

Slice thinly or dice(based on your preference) the red onion and add it to the spinach.

Clean the strawberries, remove the stems and slice them thin. Add them to the spinach.

Add the cooled chopped walnuts.

Optional, add chopped crisp bacon.

Sprinkle crumbled Feta cheese or goat cheese over.

Make a vinaigrette with oil, vinegar(or lemon juice), salt and pepper and pour over the salad.

Toss gently the ingredients in the bowl, so they get coated with the dressing. Taste and add more salt if necessary.

Serve immediately.
