If you don't have a lot of time, but still want to eat something nutritious, then you should consider making some lentils. After you give them a good rinse, you put them in a big pot, cover them with water, let it boil and then simmer for 20 minutes more or less. When they are ready, chop one onion and lots of garlic. On a separate pot, add some olive oil and fry the onions and add the garlic. Add a ladle of lentils and some seasoning like onion powder, garlic powder, salt, pepper, whatever you like in your food. I like hot chilly powder and sometimes a bit of Indian spices. Stir everything together and pour on the pot where the lentils are. So easy and so good!
You're probably going to end up eating everything, but if you don't, here's something delicious for you to do with the leftovers:
Leftover lentils (just the lentils, not the saucey part) - I used about 3 cups
2 Tbsp tahini
4 cloves garlic
1 Tbsp Tamari
Put everything in a food processor or a blender and EAT! Soooo good you won't believe it!
