Marjoram is in the oregano family but to me, it has more of a lemony flavor. I don't really use it too much in cooking but there are a couple of standby recipes that use it - rice pilaf with orzo and another zucchini feta chickpea dish from one of the Moosewood cookbooks.
This is the season for cold salads for me so I decided to make a pasta/white bean/tuna salad with the herb
White Bean, Tuna and Pasta Salad
Open a can of navy beans or canellini beans and rinse well. Toss in a bowl and add a can of chunk light tuna that has been drained. Boil as much pasta as you would like (I used elbows). Toss with beans and tuna. Make a vinaigrette with lemon juice and olive oil. Salt and pepper to taste. I added chopped marjoram and chives along with some chopped garlic scapes. I also had some cherry tomatoes and diced carrots from the garden. Mix well.
