Slice the pepper. Removing any seeds and pith.
Dice your onion finely.
Drain and rinse your mixed beans thoroughly.
Set your Ninja Foodi to the brown/sauté mode.
Add a little oil and your beef mince.
Break up using a wooden spoon to avoid scratching the pot.
Season with salt and pepper.
Lightly brown the mince.
Turn off the sauté mode.
Add the pepper, onion, mixed beans, chopped tomatoes, beef stock and Mexican spice blend.
Stir well.
Close the pot, sliding to the pressure cooker setting (or adding the pressure cooker lid if you have an older model).
Set the pressure to high, for 4 minutes.
Make sure the valve is sealed.
Leave it to cook for the 4 minutes, remembering that it can take around 10 minutes for the pressure to build in the pot before the timer starts counting the 4 minutes cooking time.
Quick release the steam. I always use an oven glove and then a wooden spoon to turn the vent to ensure that I don't get hurt by the steam, as it is VERY hot and WILL burn you if it comes into contact with your body.
Serve with rice, I love to serve with Ninja Foodi white rice. We also have lots of sauces, and lovely toppings such as grated cheddar cheese and a little mozzarella. Yum!
