Happy Passover!

Hello! Happy Passover!
Recipes:
Huevos Hominados:
4 or 5 cups packed outer skins of onions
12 large eggs, in the shell (make sure the shells have no cracks)
2 tablespoons coffee grounds
2 tablespoons olive oil
2 teaspoons vinegar
1 teaspoons salt
1/2 teaspoon black pepper
Chicken soup with asparagus and shiitakes, served with roasted fennel matzoh balls:
Matzoh balls:
2 small to medium fennel bulbs (I used one large one)
2 tablespoons olive oil
1/2 cup chicken broth, preferably homemade, or good-quality, low-sodium purchased
1 tablespoon coarsely chopped garlic
3/4 teaspoon chopped fresh thyme
1/4 teaspoon fennel seeds ground in a spice grinderor with a mortar and pestle (optional)
~1/2 cup plus 2 tablespoons matzoh meal (substituted with flour)
Soup:
7 cups chicken broth
1/4 lb fresh shiitake mushrooms (substituted with baby bella)
12 to 15 thin asparagus spears, trimmed and cut into one-inch pieces
Honestly, I was kinda confused as to why there was no chicken included too.
