'Healthier' alternative to cured meats for egg scramble?

I make a kind of egg scramble with cured meat, cheese and veggies every single day (for gains). I've heard online that eating cured meat often (like I do every day) is bad for you due to the nitrates in it, which can increase the risk of cancer. Now I wonder what might be a better alternative for an egg scramble for which I basically use the same ingredients as a frittata, but instead of putting it in the oven I first fry the meat and veggies and then add the beaten eggs & cheese and scramble it together in the pan.

I use cured meat because I know that a frittata is also usually made from it and I try to stick to that, also the meat (I usually choose chorizo as it's the cheapest where I live) has fat which once rendered I fry the veggies in. Also the salt is nice to season everything.

Now I'm not even sure if eating the cured meats that often is even that big of a deal (I only add 30 grams of cured meat), and if it is, does anyone know a meat that can offer good fat content and great flavor for this specific instance? Thanks
