Bring a large pot of salted water to a boil. Add the pasta and cook according to package instructions until al dente, then drain and set aside.
Heat the olive oil in a skillet over medium heat. Add the minced garlic and cook until fragrant, about 30 seconds, until it just starts to turn golden.
Add the halved cherry tomatoes to the skillet. Cook them for about 2-3 minutes until they soften slightly and start to release their juices, filling the pan with a bright aroma.
Stir in the chopped spinach and cook until wilted, about 1-2 minutes, which will deepen the green color and make the mixture lively and vibrant.
Add the cooked pasta to the skillet and toss everything together, allowing the flavors to meld. Season with salt and pepper to taste, adjusting as needed.
Gently fold in the crumbled feta cheese, letting it melt slightly into the warm pasta and sauce, creating creamy pockets with each bite.
Give everything a final toss to ensure an even distribution of feta, tomatoes, and spinach. The pasta should be glossy and colorful, with a light sauce coating each strand.
Serve the pasta hot, garnished with extra feta or fresh herbs if desired. Enjoy the vibrant, fresh flavors and tender textures in every bite!
