A hearty pasta dinner need not require multiple pots. For less effort and post-meal cleanup, why not cook everything together?
By using the exact amount of liquid necessary to cook your pasta with the other ingredients, you do away with requiring an extra pot of water for your noodles and the need to pull out the colander. Shredding your sweet potato is a hack that lets it cook in a flash (also try this when making hashes, stir-fries, and grain bowls), while baby greens are a nutritious no-chopping-required add-in.
You don’t need to crank up the oven to make a small batch of toasty nuts. Instead, nuke them. Spread nuts in a single layer on microwave-safe plate. Microwave on high power for 1 minute, stir, and continue heating in 30-second intervals, stirring between each interval, until nuts are fragrant and a few shades darker.
Per serving:
In large pot over medium, heat oil. Add meat and heat until browned, about 4 minutes. Remove from pan and set aside. Add onion; heat until onion has softened, about 5 minutes. Add sweet potato and garlic; heat until potato is tender, stirring often, about 3 minutes.
Add pasta, broth, canned tomatoes, tomato paste, lemon zest, Italian seasoning, and red pepper flakes to pan. Bring to a boil; reduce heat to medium-low and simmer, covered, until pasta is al dente and liquid has almost evaporated. Be sure to scrape up any brown bits from bottom of pan. In batches, stir in kale until wilted. Stir in ground meat and heat through. Remove from heat and let stand for 5 minutes. Garnish with Parmesan and a splash of lemon oil if desired.
