1. Cut your tempeh into ¾-inch cubes—you want them substantial enough to hold their shape during cooking.
2. Heat the olive oil in your largest skillet over medium heat until shimmering. Add the tempeh cubes in a single layer and let them cook undisturbed for 2-3 minutes per side until lightly browned on most sides, about 5 minutes total. Don’t constantly move them—they need contact with the hot pan to develop that golden crust.
3. Add the sliced celery, red bell pepper strips, sliced onion, and minced garlic to the skillet with the tempeh. Cook everything together for about 5 minutes, stirring occasionally, until the vegetables start to soften and the onion turns translucent.
4. Pour in the canned diced tomatoes with all their juices—don’t drain them. Add the dried oregano, basil, red pepper flakes, salt, and black pepper. Stir everything well to combine and coat the tempeh and vegetables.
5. Reduce the heat to low, cover the skillet, and let it simmer gently for 15-20 minutes, stirring occasionally. The celery should become tender but still have a bit of bite, and the sauce should thicken slightly.
6. Taste and adjust seasoning—tempeh absorbs a lot of flavor, so be generous with salt. The mixture should be saucy but not soupy.
7. Serve hot, garnished generously with fresh chopped parsley. This is fantastic over pasta, rice, polenta, or with crusty bread.

Notes:

• Brown the tempeh well for best flavor and texture
• Don’t drain the canned tomatoes—the juice becomes your sauce
• Fresh, crisp celery holds up better than old, limp celery
• Dried herbs should smell potent—replace if they’re old
• The dish thickens as it sits; add liquid when reheating
• Don’t skip the fresh parsley garnish—it brightens everything

Storage Tips:

Store in an airtight container in the refrigerator for up to 5 days. This actually tastes better the next day after flavors meld. Reheat gently on the stovetop over low heat, adding a splash of water or broth if needed. Freeze in portions for up to 3 months in freezer-safe containers. Thaw overnight in the fridge and reheat gently. The tempeh continues to absorb flavor as it sits, making leftovers even more delicious.
