Chicken soup is super easy! I like to roast my own chicken and make a stock from that, but that is admittedly very time consuming. You can also boil bone-in chicken thighs, use meat that's already cooked along with pre-made broth or bouillon, or even use leftover rotisserie chicken from the store.These look delicious! Especially the soup. Thanks for sharing. When I live on my own again I'm going try these recipes.
For a basic chicken soup I sauté the onion and garlic in a Tbsp of oil and a splash of seasoned vinegar (notice a theme?

And for the matzo I honestly just use Manischewiz matzo and follow the instructions on the back: you basically beat an egg and some broth into the matzo mix, chill for 10 minutes, form into balls, and plop them into the soup to cook.
