Add the olive oil to a skillet over medium heat. After a minute or two, add the sliced sausage and cook through completely - about 5-7 minutes, stirring occasionally. It's okay if it sticks a little or there are brown bits in the pan.
When the sausage is cooked through, add the chopped broccoli, orzo, veggie broth/water, 2-3 squeezes of lemon juice, minced garlic, salt and pepper to taste and crushed red pepper if using. Stir well to combine and bring the mixture to a boil, then reduce to a simmer, cover and cook for 15 minutes.
After 15 minutes, take a bite of the pasta. It should be soft and completely cooked. If it's sticking to the pan a lot and isn't totally cooked through, add a few more tablespoons of broth/water. If there's too much water left in the pan, cook uncovered until it evaporates.
When the orzo is done cooking, add the remaining lemon juice wedges and stir in the parmesan cheese/nutritional yeast if using.
To assemble: divide the mixture into 3 meal prep containers. That's it!
