This makes a hearty vegan brunch dish that reheats well.

The trick of a nice frittata is to flip it on a plate and slide it back into the pan.
With tofu, it is essential to brown the bottom of the frittata to keep it from falling apart when it is turned (the tofu crumbles more easily than the traditional egg)
I like to use a non-stick "everything" pan for this dish

Step 1: Assemble Your Tools

Essential equipment:

Frittata pan or "everything" pan (a regular skillet works as well)
Chef's knife (for chopping firm vegetables, such as onions)
Serrated knife (for slicing soft vegetables, such as tomatoes)
Cutting board
Spatula
Plate (for turning, unless you have a two-sided frittata pan)
Potato masher (for mashing tofu)

Step 2: Gather Ingredients

14-16 ounces Tofu (one typical block, extra firm, drained)

4-6 leaves Tuscan (lacinato) kale

6-8 oil-packed Sun-dried tomatoes (or pre-soaked, plain sun-dried tomatoes for lower fat recipe)

1/2 medium Onion

1-2 cloves Garlic

2 Tablespoons Nutritional Yeast

1/4 Teaspoon Garlic Salt (or plain sea salt)

1/4 Teaspoon Kala Namak salt (provides sulfur-egg aroma, use sparingly)

Dried herbs: oregano, marjoram, thyme, etc. to taste

Sunflower oil (or vegetable broth) for sauteed vegetables

Optional:

Fresh herbs to taste

Step 3: Prepare the Kale

Wash kale thoroughly to remove grit
Remove tough kale stems by pulling the dark green part away from the lower part of the leaf

Step 4: Prepare the Vegetables

Chop or mince the onions and garlic and any fresh herbs (if used);

Slice the soft vegetables (sun-dried tomatoes, peppers, greens, etc.

A sharp chef's knife makes quick work of most chopping tasks, but a serrated knife slices soft vegetables without crushing or tearing them.

Step 5: Saute Onions and Garlic

Saute onions and garlic over medium heat until translucent (also saute any firm vegetables, including kale stems, if not discarded)

Step 6: Add Kale and Tofu

Add kale and tofu to sauteed onions and garlic
Add herbs and seasonings
Mash ingredients together with potato masher

Step 7: Adjust Seasonings

It is important to adjust the flavor before the tofu fuses together into a solid "cake" (I often choose to add more Nutritional Yeast; it is an acquired taste, so tread carefully)
