Well Yeh kinda obvious that bit mate I put a slice of pizza between two slices of buttered bread back in my pot noodle and hash days, would recommend for anyone below the poverty line tbh.
So, bolognese sauce instead of just tomato sauce. Sounds a winner to me. FWIW, do it with chilli. Proper pizza that, fookin' delicious.
Youre assuming @Quesadaad didn't just spoon some Bolognaise on a standard frozen pizza though. But regardless, your suggestions are good ones and they would deffo work for me.
