I loosely follow eric kim’s recipe below for the tuna, some marinated tofu would also work well. Then I make a big pot of rice, and add whatever toppings I have on hand throughout the week (kimchi, cucumber, cilantro, sesame seeds, all things that require very little of you and can be done ahead)
For the lentils, I make a big pot at the beginning of the week and again, top with various things I have around (an egg, a handful of arugula, lemon, yogurt, garlic)
I find that having two bases that are different enough and customizable keeps feeding yourself simply from feeling like a punishment while you focus on other things.
ps: if you’re new to lentils, lemme know, i’ll write out my recipe for ya!
