Grab a large pot or deep skillet – the bigger, the better for mixing everything later. Heat up that tablespoon of olive oil over medium heat.
Toss in your diced bell peppers and onion. Give them a stir and let them cook until they start to soften up, which usually takes about 5-7 minutes. You want them tender-crisp, not mushy!
Now, add the pound of ground beef to the pot. Use your spoon to break it up into crumbles as it cooks. Keep stirring until it's completely browned. Once it's cooked through, it's a good idea to drain off any extra grease – nobody wants a greasy pasta dish!
Stir in the minced garlic and cook for just about 1 minute more. You'll smell that amazing garlic aroma as it hits the hot pan! Be careful not to burn it.
Pour in the entire jar (or two small jars!) of your pasta sauce. Stir in the Italian seasoning, garlic powder, onion powder, and season generously with salt and black pepper to your liking. Give it all a good mix to combine.
Bring the mixture up to a gentle simmer. Once it's simmering, reduce the heat to low, cover, and let it cook for at least 10 minutes. This is where the flavors really get to know each other and deepen. If you have a little extra time, letting it simmer longer (even 20-30 minutes) just makes it even better!
Finally, add your cooked bowtie pasta right into the pot with the sauce. Stir everything together until all the pasta is coated in that delicious, savory stuffed pepper-inspired sauce.
Serve it up hot and watch it disappear!
