Cook it safe

160°F / 71°C — Ground beef, pork, veal, and lamb, measured in the center of the thickest part.

Refrigerate leftovers within 2 hours of cooking — within 1 hour if the room is above 90°F / 32°C.
Reheat leftovers to 165°F / 74°C before serving.
Use a calibrated instant-read thermometer rather than color or cooking time to judge doneness.

Temperatures follow the USDA Food Safety and Inspection Service safe minimum internal temperature chart.

Nutrition is estimated from the listed ingredients using standard reference values (USDA FoodData Central). 4 of 5 matched ingredients use verified FoodData Central entries (dictionary snapshot 2026-09-11). Brand, portion, and preparation differences can change the result. Frying fat is counted at the share typically absorbed, and brines drained before cooking are excluded. These figures are an estimate for general interest, not medical or dietary advice.

Equipment

Electric griddle / flat-top

A flat-top holds one temperature across the whole surface, so every tortilla and egg in a batch cooks at the same rate.

Instant-read meat thermometer — This recipe has a target internal temperature, and color is not a reliable way to read it.
Burger smasher / bacon press — Firm, even pressure is what maximises contact with the surface and builds the crust.
