I actually came up with this by accident (I had leftover rice and lentils) and it happens to taste REALLY good, hot or cold.
Boil the brown rice as per the instructions on the package (Other wise, boil the rice and water with the boullion cube until fast bubbles and then turn heat to half and cover for 45 minutes, rice should be nice and fluffy)
As for the lentils, I went the easy way and used canned lentils but by all means, please prepare them as you wish. Rinse and add 1/4 cup along with the chopped onions and toasted almonds (lightly brush almond pieces with sunflower oil and place on broiler or in toaster oven.)
And that's it! It tastes yummy!
