1 tablespoon onion powder
2 teaspoons ground cumin
½ teaspoon salt
½ teaspoon ground pepper
½ teaspoon ground coriander

The peppers and onions bring that sweet crunch with a bit of roasted charm after pressure cooking. Grab your toppings too: pico de gallo for freshness, sour cream for smoothness if you’re into dairy, and cilantro to freshen it all up. Wrap these up in tortillas and you’re good to go for a fast flavorful dinner.

The Full Pressure Cooker Journey

Start by mixing garlic powder, onion powder, ground cumin, salt, pepper, coriander, smoked paprika, and chili powder in a small bowl. Add the olive oil and juice of 2 limes, whisk to combine.

Thinly slice your London broil, bell peppers, and onion strips. Toss these into a big bowl with the marinade. Mix well so every piece gets some love.
Set your pressure cooker with the sealing ring in place. Add the marinated beef and veggies to the cooker pot evenly spread out.
Lock the lid and start the pressure build on high. Watch the float valve rise to make sure it’s sealing good.

Cook under pressure for about 10 minutes, just enough to get the meat tender but veggies won’t turn to mush. You gotta check broth depth; don’t add too much liquid or it won’t fry right.
Hit quick release to let out the pressure and open cooker carefully. You’ll notice the colors on your peppers still poppin and steak juicy.
Sprinkle with chopped cilantro and squeeze juice from the last lime over everything for that zingy finish.

Serve with warm tortillas, pico de gallo, and sour cream if you want. Wrap ’em up and dive in!

Valve Hacks You Need to Know

Before sealing, always check if the float valve moves freely and isn’t stuck from old gunk.
Keep a little wet cloth nearby to clean the sealing ring after each use, that ring’s gotta be clean for the best seal.

If your pressure cooker gets too full with liquid, don’t pressure cook too long or veggies get soggy. Adjust broth depth by eyeball.
Quick release means you unload steam fast so peppers don’t overcook. Don’t skip it on fajitas or you lose crunch.
After cooking, let your cooker rest closed for a minute or two, that helps distribute heat and flavor more even.

The Flavor Experience Waiting for You

When you bite into these fajitas, you first get hit with a smoky warmth from the paprika and cumin, like a perfect campfire night. Then the fresh lime juice kicks in making it bright and lively on your tongue.

The thin strips of London broil soak up the marinade so every chew is tender with a bit of tangy zest. The peppers and onions keep their fresh crunch despite being cooked, adding that sweet balance to the spices.

That little sprinkle of cilantro on top gives it a fresh herbal note that kinda cleanses your palate and makes you wanna take the next bite right away.

Overall it’s like a flavor party going on in your mouth, smoky, tangy, sweet, and fresh all at once. You’ll wanna make this one again faster than you think.

Making It Last All Week Long

If you got leftovers, no worries, they store up real good. First, cool your fajita mix to room temp before packing it in airtight containers. That helps avoid sogginess later on.

You can keep these in the fridge for about 3-4 days. Just reheat gently on the stove or microwave so you don’t dry out the meat and veggies.

For longer storage, throw the fajita mix in freezer bags and freeze up to 3 months. Thaw overnight in the fridge then warm up for a quick dinner that tastes nearly fresh.
