Bring lentils, broth, garlic, ginger, turmeric, cumin, coriander to a boil. Reduce heat to medium low and simmer, covered for 25 to 30 minutes until lentils are softened but not mushy.
While lentils cook, start rice. Bring rice, broth, turmeric, cumin, coriander to a boil. Reduce heat to low. Simmer covered for 12 minutes until rice is fluffy. Rice may still be a bit soupy, but that is okay.
Add rice to lentil mixture. Stir, cover, and simmer an additional 5 minutes to heat through.
Served garnished with parsley and/or red pepper flakes as desired.
