If you're Italian-American and grew up eating macaroni and peas in red sauce like me, this dish is probably more like nostalgia in a bowl than anything else.

Instructions
Heat the olive oil in a 2-quart pot over medium heat. Add the onions and ¼ teaspoon of salt. Cook the onions until soft and translucent but not brown, 5-7 minutes.
Add the garlic powder, tomato sauce, and peas, and simmer with the onions for 1 minute while stirring.
Pour in the water, pasta, and ½ teaspoon salt, and bring everything to a boil. Reduce to a simmer, cover the pot partially with a lid, and cook until the pasta absorbs most of the liquid and is al dente, about 15 minutes.
If the pasta needs more cooking time and there isn't enough liquid, pour in an additional ½ to 1 cup of water and simmer for a few more minutes before removing from the heat.
Add ground black pepper, and taste for salt, adding more if needed.
Serve the pasta and peas topped with grated Pecorino and some extra ground black pepper, if desired.
Notes
Note 1: You can defrost the peas if you want, but it's not necessary.Note 2: If you want a soupier dish, add 2 and ½ to 3 cups of water. You may need to add more salt if you do this.
