Quick pantry pasta with canned tuna, tomatoes, and olives makes a no-fuss mediterranean meal. High in protein and ready in minutes, it's perfect for a healthy family dinner on a calorie deficit.
Bring a large pot of salted water to a boil, then cook the penne pasta until al dente following package instructions; reserve 1 cup pasta water before draining.
Meanwhile, in a large skillet over medium heat, warm the extra-virgin olive oil. Add chopped shallot and sauté for 2 minutes until softened, then stir in minced garlic and red pepper flakes for 30 seconds, keeping heat moderate to prevent browning.
Pour in the crushed tomatoes and simmer for 6–8 minutes on medium-low heat, stirring occasionally, until slightly thickened.
Fold in drained tuna (crumbling with a fork) and sliced olives. Season with salt and black pepper, and cook for 2–3 minutes to combine flavors, ensuring the mixture doesn't dry out.
Add cooked penne to the skillet and gently toss over medium-low heat, adding reserved pasta water as needed to achieve a silky sauce that coats the pasta evenly. Serve immediately.
