Heat up olive oil and add garlic. Let garlic cook for a minute and then add tomatoes, tomato paste, oregeno, and basil. Bring to a boil and then add the 4 cups of water and the bullion cube. Bring to a boil again. Once it boils add the pasta and cook until pasta is tender.
This is good served with croutons or crusty vegan bread. I just drop some croutons onto the top of each bowl of soup.
Also if you don't have the bullion cube it works just fine without it! It just adds a little extra flavor.
For the pasta I like using elbow macaroni, but broken up spaghetti, or any other leftover pasta works fine.
