Pour water into an electric
pressure cooker and
place a trivet in the cooker.
Arrange the whole zucchini
on the trivet, angling as
needed to fit.
Place lid on the cooker
and make sure the vent
valve is in the Sealing
position. Using the display
panel, select the Manual/
Pressure Cook function
and High Pressure. Use
the +/− buttons until the
display reads 4 minutes.
While zucchini cooks,
heat a large skillet over
medium-high heat. Once
the pan has preheated,
add olive oil. Add onion
and cook, stirring occasionally,
until softened,
about 5 minutes. Add
chicken, salt, garlic powder,
black pepper, basil, thyme
and oregano. Break up the
chicken and cook another 5
minutes.
Stir in marinara sauce
and reduce the heat to low.
When the cooker beeps,
switch the vent valve from
the Sealing to the Venting
position, administering a
quick release. Use caution
while the steam escapes.
Carefully transfer
zucchini from the cooker
to a cutting board. Once
cool, cut in half lengthwise
and scoop out the seeds,
leaving a ¼-inch shell.
Scoop a few tablespoons
of chicken mixture into
each boat and sprinkle
with the parmesan.
