It's actually VERY easy to come up with recipes that don't involve dairy ingredients. Start by looking at Jewish recipe sites. Jews who keep kosher have three separate categories of foods. There's meat (anything involving meat or meat byproducts, such as broth); dairy (anything involving dairy ingredients or byproducts, including casein and whey); and parve (anything that involves neither meat nor dairy. Just pick recipes that say Meat or Parve, because meat recipes aren't allowed to contain any dairy products or byproducts (and vice versa, but that's not important), and parve means that there's no dairy or meat (grains, vegetables, fish, eggs, fruits).
Also, look for canned or boxed goods that have a
symbol for a kashrut supervision agency, that either don't have a D or DE (both of which stand for dairy), or that do have a Meat designation on them.
