Cook and drain the extra lean ground beef.
Preheat the oven to 375F, and spray a 9x13 casserole dish with some nonstick cooking spray.
Dice the onion and add it to a bowl with the extra lean cooked ground beef, pasta sauce and seasoning. Mix it all together really well.
Cut up the 10 small biscuits into 6 small pieces each (60 pieces in total)
Pour half of the meat mixture into the bottom of the casserole dish.
In a small bowl, mix the ricotta, egg whites and pesto together. Drop by small spoonfuls onto meat mixture and spread around covering as much as you can.
Evenly place the small biscuit pieces on top of the ricotta.
Add the remaining meat mixture, then top with the cottage cheese. Sprinkle the parmesan cheese on top.
Bake in the oven uncovered for 25 minutes. Remove from the oven, sprinkle on the mozzarella cheese, and return to the oven for 10 minutes.
Remove it from the oven, let it cool for a bit, then cut into 6 equal servings.
