I first get a pot of water boiling for the pasta. While that's going, I season both sides of the chicken tenders, put about a tablespoon of olive oil in a non stick pan, and then add the tenders to the already heated (medium-high) pan. Let those brown up on both sides and remove from pan. Add pasta to boiling, salted water. As the chicken cools, I start making the sauce (or putting it together, it is already "made").
Sauce: in the same pan, add the whole can of tomatoes, and scrape up the browned chicken bits. Then add the jar of spaghetti sauce. Simmer on medium heat.
Back to chicken: tear the chicken into pieces and add to sauce. *This is the part that my dogs LOVE, because they know that I will toss the yucky bits of chicken to them!* stir in the chicken. Drain the pasta. Fix your plate, add parm cheese if you desire!
