I was super impressed with it. Below is the recipe I used. I made it with a whole package (16oz) of spaghetti noodles and 3-1/2 cups of water (maybe I put some Chicken flavor "Better than Bouillion" in with that water - I can't remember now, but I think I probably did). This made a boatload of spaghetti, and I do mean a BOATLOAD! Had to be at least 8 large servings. We were eating spaghetti for days (but it refrigerates or freezes well). I used a higher end jarred marinara sauce, not one of the cheapies. I don't remember which brand it was, but it was like $6 a jar vs. $2 a jar for the cheapies. And the chopped tomatoes definitely added to the taste (I used finely chopped/diced canned tomatoes). I also used fresh basil from the produce section, chopped up finely. I used the el-cheapo jar of Italian Seasoning though - I don't know what's in those "Italian Seasoning mixes" to substitute fresh ingredients, but the dinner came out fine with that cheap jarred seasoning. And definitely grated Parmesan cheese in a plastic package from the dairy section, not the dried powder that Kraft makes in those green plastic cans. That dairy cheese melts in there and adds a lot more flavor than the dried powder stuff.
When making it, you break the noodles in half (I have a large Instant Pot, smaller ones might need them broken in thirds) and then scatter them randomly. I was pretty anal about spreading them out randomly, so I didn't have any clumps where they stuck together. The liquids are then poured in over the noodles, without stirring or disturbing them. Then after adding the liquids I gently pushed the noodles down with my hands so they were submerged.
