Cook the lentils on the stove or instant pot. Make sure not to overcook – you want them slightly al dente and not mushy.
Add the macaroni to a pot of boiling water, cook, and drain.
Cook brown rice until perfectly fluffed, or the sorghum until it's done without being soggy.
Make the tomato sauce: saute half an onion and all the garlic in a pan. Add the tomatoes or tomato sauce.
While the sauce simmers – chop up the remaining onions into thick strips. Spread on a baking tray and grill on medium heat until the edges are crispy.
Then add the vinegar, cumin, chili powder, and salt and pepper to taste to the tomato sauce. Once it's absorbed the spices, remove from heat.
Serve by layering the rice, macaroni, lentils, and tomato sauce, then top with grilled onions.
