Confession time – I stole this recipe from Hello Fresh. and it cost me a whole lot less to make myself than ordering through them! I had everything at home except the chicken sausage, spinach, and grape tomatoes, which cost me about $10.
Heat olive oil in a large, tall-sided pan over medium-high heat (use an ovenproof pan if you have one). Add sausage, and cook until just browned, about 3 minutes.
Add tomatoes and garlic to pan with sausage. Cook, stirring occasionally, until tomatoes start to wilt, 2-3 minutes. Add orzo Italian seasoning. Cook, stirring, until orzo is coated in juices, about 1 minute. Season with salt and pepper.
Add chicken stock to the same pan. Bring to a boil, then lower heat to medium. Let simmer, stirring occasionally, until orzo is almost al dente, 7-9 minutes. Stir in chopped spinach and cook until wilted, about 3 minutes more. If mixture seems dry, add water ¼ cup at a time until loose.
Stir mozzarella and the juice of the lemon into pan. Season with salt and pepper if needed. If your pan is not ovenproof, transfer mixture to a baking dish at this point. Sprinkle panko and Parmesan over top of orzotto. Broil until panko is golden brown, 1-3 minutes.
