As PF said, pulsing is your answer. Keep an eye on it. Start with just a few pulses. Are the pieces small enough yet? No? Then a couple of more pulses. Continue in this manner until they are the size you can swallow them without chewing. Also, to keep your meals interesting, don't toss everything in together. Different foods require different amount of pulses. Soft veggies like green beans only require about three pulses, whereas meat requires more. For myself, I wouldn't put gravy in while processing. It only hastens the mushiness. Heat up the gravy in the zapper and add it after your food is on your plate.
If you pulse carefully, you can end up with a plate of food that is appealing and looks like it was meant for a toddler. Not a newborn.
